FAQs

Orders & Payment

We accept Visa, Mastercard and American Express, as well as PayPal, Apple Pay and Google Pay [to confirm]. Your card is charged when you place your order. Only one form of payment may be applied to an order.

Yes. At checkout, you can choose to split your total into smaller payments with no additional charges or interest. Installments are collected automatically, and the amount of each one is shown before you confirm.

Our warehouse processes orders quickly, but you can cancel or change your order within one hour of placing it. To do so, email us at [support email] with your order number. After that, your order is being processed for shipment and can no longer be cancelled or changed. If your order has already shipped, you can request a size exchange or a return once you receive it.

First, check your spam or promotions folder. If you still can't find it, contact us with the name and email address used to place the order and we'll resend your confirmation.

We're working hard to restock this size as soon as possible. On the product page, select your size and click "Notify me": you'll be among the first to know by email as soon as it's back in stock.

It's in your order confirmation email. You can also find it in your account, under your order history, and on the packing slip inside your parcel.

Once an order is placed, please allow 1 to 2 business days for it to be packed and shipped. Upon shipment, you'll receive an email with your tracking number. Tracking can take 24 to 48 hours to start updating after your order ships. Delivery then takes 2 to 5 business days in France and 7 to 15 business days internationally. If your tracking says delivered but you don't have it, check your mailbox, your building's concierge and your neighbours, then give it up to 24 hours: carriers sometimes scan early. After that, contact us with your order number.

If the estimated delivery time has passed and your tracking has stopped updating, or if your parcel is marked as delivered but you haven't received it, contact us with your order number. We'll open an investigation with the carrier and, if the parcel is confirmed lost, we'll resend your order or refund you, whichever you prefer.

Shipping & Tracking

Yes, standard shipping is free on orders over $60. Below that, shipping costs depend on your destination and are shown at checkout before you place your order.

Please allow 1 to 2 business days for processing, then 2 to 5 business days for delivery in France and 7 to 15 business days internationally [to confirm]. Exact delivery times for your country are shown at checkout. During periods of high demand or bad weather, please allow for potential carrier delays of 3 to 5 business days.

Once your order ships, you'll receive an email with a tracking link. You can also find your tracking in your account, under Orders. Without an account, use the Track Your Order page with your order number and the email used at checkout.

Yes, we ship to [list of countries, to confirm]. Select your country from the dropdown at the bottom of the site to see prices in your local currency. Shipping fees and delivery times for your country are shown at checkout.

Within one hour of placing your order, email us at [support email] with your order number and the new address. Once your parcel has shipped, we can no longer change it: contact the carrier directly from your tracking link to have it redirected. Please note this may extend the delivery time.

It's normal for tracking to take 24 to 48 hours to start updating after shipment. If your tracking hasn't moved for more than 5 business days, contact us with your order number and we'll open an investigation with the carrier.

Some carriers scan a parcel as delivered while it's still out for delivery, and drop it off within the next few days. Check your mailbox, your building's concierge, your neighbours and the pickup point. If after 4 business days you still have nothing, contact us with your order number.

Items from the same order are sometimes shipped separately. In that case, you'll receive a shipping email and a tracking number for each parcel. Check your inbox: the second parcel is on its way.

Returns & Exchanges

You can return your order within 30 days of delivery for a refund or store credit. Items must be new, unworn and unwashed, with tags attached, in their original packaging. Refunds are issued to the original method of payment. If it's a sizing issue, there's nothing to send back: see our Perfect Fit Guarantee below.

It's covered by our Perfect Fit Guarantee. Email us within 30 days with your order number and the size you need: we'll send you the new size free of charge, and you keep the first one.

Yes. Try it on at home, on clean skin, without perfume or lotion, and keep the tags on. If within 30 days you'd rather return it, it will be accepted as long as it's new, unworn and unwashed.

Contact us at [support email] with your order number and the item concerned, and let us know whether you'd like a refund or store credit. We'll send you the instructions and the return address. Once we receive your parcel, your return is processed within 2 to 3 business days.

Yes if you choose store credit: we cover the return shipping. If you choose a refund, return shipping is at your expense and original shipping fees are non-refundable. No fees in any case if the item is defective or if we made a mistake.

Final sale items, free items, gift cards and any item showing signs of wear. These exclusions don't apply if the item is defective or not as described.

Yes, within 30 days of delivery, as long as the item is new and unworn. Contact us at [support email] with your order number and the item you'd like: the new item ships as soon as your return is scanned in transit. Items cannot be exchanged more than twice.

Once your parcel is on its way back to our warehouse, the return process has started. Track it with the tracking number of your shipment. When it arrives, we inspect it within 2 to 3 business days and send you a confirmation email.

Your return is processed within 2 to 3 business days of receipt. The refund then shows up in your account within 5 to 10 business days depending on your bank, to your original payment method. After 10 days, contact your bank first, then us if they can't find it.

Send us a photo with your order number within 30 days. We'll send you the right item, or refund you, free of charge and without waiting for the return.

A manufacturing defect that appears within [3 months, to confirm] of purchase is covered: send us a photo and your order number and we'll replace the item. After that period, normal wear and tear is not considered a defect.

Size & Fit

Use our "Find my size" tool on the product page: it starts from the size you wear today and gives you your UNDR size in a few clicks. If you don't know your band and cup size, take your measurements (see below) or write to us, we're happy to help.

With a tape measure, without a bra or wearing an unlined bra. Underbust: just below the breasts, tape level and parallel to the floor. Bust: around the fullest point, without pulling tight. Enter both measurements in our size calculator.

Each UNDR size covers several standard band and cup sizes. The size chart on the product page gives the exact match, for underbust measurements from 58 to 102 cm and cups A to G. The "Find my size" tool does the conversion for you, including from international sizes.

Take the larger size. And if it doesn't fit, our Perfect Fit Guarantee has you covered: we'll send you the other size free of charge within 30 days.

Our bras are designed for cups A to G, with an underbust from 58 to 102 cm. Use "Find my size" on the product page to find your fit.

JellySupport™ is our soft, flexible alternative to traditional underwire support, designed to give you the lift and stability you need without the rigid pressure.

Our W-shaped gel support system sits beneath the cups and extends along the sides. Instead of relying on rigid structure and concentrated pressure against the body, it flexes with you while helping lift, shape, and stabilize the bust.

By spreading support across a wider area, JellySupport™ helps reduce the feeling of concentrated pressure for a more balanced, comfortable feel throughout the day.

In short: support that moves with you, without the rigid feel.

Choose the size that fits your larger breast. The moulded cups keep their shape and smooth out the difference on the other side.

In the right size, your bra lifts and supports, the band sits level at the front and back, the centre lies flat against your breastbone, the cups are filled without spilling and nothing digs in. If that's not the case, change size: exchanges are free within 30 days.

Too tight, it digs in, restricts your breathing or leaves marks that don't fade: take the next size up. Too loose, it rides up at the back and the straps slip because they're carrying all the weight: take the next size down. Either way, the exchange is free.

Cups gaping at the top: shorten the straps a little, and if the gap remains, take the next cup down while keeping the same band. Spilling over the top or sides: take the next cup up, same band. If the band fits, don't change it.

If the cups fit but the band doesn't, a sister size keeps the same cup volume with a different band: a looser band with one cup letter less, or a tighter band with one cup letter more. The size chart shows you yours.

Not by default. It depends on how your bust and underbust change: measure yourself when you order and follow the size chart. If your size changes afterwards, you have 30 days from delivery to request another one free of charge.

Don't start from your old size. Take your measurements today and follow the size chart, or redo "Find my size". If the shape has changed more than the volume, the moulded cups fill the top without gaping. And if you're unsure, write to us.

Product & Care

A soft, W-shaped gel band built in under the cups and along the sides. It replaces the underwire: it lifts and shapes, with no rigid wire, and moves with you. The moulded cups add shape and support, while the wide band and flat back keep everything in place.

No. The cups are smooth, the edges are bonded with no seams, and the wide, flat back leaves no ridge. Under a thin t-shirt, nothing shows.

No. Each cup is moulded separately: your breasts are supported, separated and keep a natural shape.

55% nylon, 45% elastane: a soft, breathable four-way stretch fabric that moulds to your shape without stretching out. No underwire, no seams under the bust. [Country of manufacture: to confirm.]

Lightweight foam built into the cups, for a clean shape and a subtle lift. No removable pads, no push-up effect.

Yes. No metal or underwire against the skin, no seams under the bust, a soft, breathable fabric. It does contain elastane: if you're sensitive to it, that's the one thing to check.

For walking, yoga, Pilates and a normal day, yes. For running, jumping or any high-impact sport, a sports bra remains the better choice.

Ideally by hand in cold water, then air dry. In the machine: in a wash bag, delicate cycle, cold water, with similar colours. No fabric softener or bleach. Lay flat or hang to dry, never tumble dry, never iron. Store it flat, without folding one cup into the other.

After two or three wears, or as soon as it has taken the sweat of a hot day. Don't wear the same one two days in a row: elastane needs time to recover its shape. Three bras in rotation, one on, one in the wash, one resting, is the idea behind the 2+1 FREE offer.

No. Heat breaks down elastane and deforms the cups. Air dried, it's dry in a few hours.

There's no set lifespan: it depends on how often you wear it and how you care for it. With a rotation of three bras, a cold wash in a wash bag and air drying, the band and cups keep their shape wash after wash. Manufacturing defects are covered for [3 months, to confirm].
