Wire-Free Silk Bras: Woven Mulberry Silk & Silk Jersey
Our collection of wire-free silk bras combines smooth mulberry silk and comfortable silk jersey styles, designed for sleep, working from home and everyday low-impact wear. With no underwire and easy back fastening, they offer gentle support without the pressure of traditional wired bras.
Woven Silk or Silk Jersey
| Fabric | What It Is | Choose It For |
|---|---|---|
| Woven mulberry silk | Four styles in 16 momme 100% mulberry silk, three of them lace-trimmed. | The lightest thing against the skin. Sleep and quiet days. |
| Silk jersey | Three styles knitting mulberry silk with spandex, around 35% silk to 65% spandex. | Stretch and shape recovery, softly padded cups, a triple-row closure that holds through a full day. |
The exact composition is stated on every product page. If you want pure silk next to the skin, filter to the woven styles.
How Much Support Do Wire-Free Bras Give
Light to moderate — enough for sleep, home and everyday wear, and not enough for running or gym work. Within that range the styles differ:
- Full-cup with adjustable straps: Holds more of the bust than a bralette and lets you set the strap length yourself.
- Lace-trim wireless: The lightest coverage, and the closest to wearing nothing.
- Silk jersey with padded cups: The most structured option here, with a triple-row hook-and-eye so you can tighten the band as the elastic relaxes.
Do silk bras actually support you? runs through the fit and comfort tests.
Getting the Size Right — Read This First
Sizes here pair a band with a cup range rather than using a single letter: S covers 70C/75B, M covers 75C/80ABC. Every product page carries its own bust measurement in centimetres and inches.
Measure and match to that chart rather than assuming your usual US size. Customers who skipped that step consistently report the cups running smaller than expected, so if you are between sizes or above a C cup, size up. A few styles are listed in Asian sizing, which runs one to two sizes smaller than US; those pages say so.
This matters more here than on any other page, because bras and underwear are excluded from the 365-day return and exchange policy for hygiene reasons — as are clearance items, and one style in this collection is a clearance piece. A wrong size is an unrecoverable order.
Silk for Sensitive Skin
Silk is a smooth protein fibre that does not scratch, and it moves moisture away from the skin rather than holding it against you. Every bra here is wire-free and fastens at the back, which removes the underwire pressure point altogether. SilkSilky silk carries OEKO-TEX® Standard 100 certification (No. 2406198), tested for harmful substances.
Washing Lace and Elastic
Hand wash below 35°C with a mild silk detergent. Swirl gently and never rub, wring or twist the straps. Rinse cool and press the water out in a towel. Dry flat or folded over a rail in the shade — hanging a wet bra by its straps stretches the elastic out of shape. Keep it away from bleach, enzyme detergents, the dryer and direct heat. Caring for silk lingerie covers lace and straps in detail.
