Frequently Asked Questions
Is this bra padded?
Is this bra padded?
No — the cups are unlined with a double layer, so they shape and hold without any foam bulk.
Does it have underwire?
Does it have underwire?
Yes. A soft encased wire cradles a fuller bust from below and gives natural lift and separation — the hold comes from the band and sides, never your shoulders.
Will it stay put on a fuller bust?
Will it stay put on a fuller bust?
That's exactly what it's made for. A grippy inner edge, a firm back band, structured sides and an encased wire keep it locked in place all day. Getting the right size matters most, and fit varies from person to person — check our size guide or message our team before you order.
How many ways can I wear it?
How many ways can I wear it?
Wear it fully strapless, or clip on the removable straps for straight, crossback, halter or one-shoulder looks. The strap options available can depend on your size.
Does it minimize the bust?
Does it minimize the bust?
The unlined cups and structured sides give a smoother, more centered line under clothing — a natural, streamlined shape rather than tight squeezing.
Will it show under my clothes?
Will it show under my clothes?
The thin mesh keeps bulk down, so it stays hidden under most tops. Any bra can show through very sheer or skin-tight fabrics, so go for the closest nude shade and a smooth outer layer for the cleanest look.

How do I care for it?
How do I care for it?
