Bandeau and strapless bras: support without straps

A strapless bra or bandeau relies entirely on the back band for support, as it lacks shoulder straps to assist it. Its hold comes from three elements: a wide, highly elastic band, lateral boning that prevents it from twisting, and an inner silicone band that stops it from slipping. Without these three, it will slide down within an hour.

Does a strapless bra support a large bust?

This is the question that determines the purchase, and the answer depends entirely on the construction. A non-boned bandeau bra won't hold up beyond a C cup. However, models designed like a short corset, with side boning, a silicone band all around, and underwired cups, can support larger cup sizes: that’s what makes a true plus size bandeau bra great size. The fit is tighter than a standard model: the band should be adjusted a notch tighter than usual, sometimes even a full band size down.

What bra for a backless dress?

The backless bra addresses a different issue: it's not the shoulder that causes trouble, but the back band, which can be visible under a low-cut dress. There are three solutions. The cross-strap, which lowers the band to the waist and runs under the back neckline. The invisible adhesive bandeau bra, which has no back at all, sticks to the skin and works up to about a C cup. And the long corset style, which stays up due to its surface area and rigidity, often the most comfortable option for a whole evening.

How to wear a bandeau bra properly

Three tips can help avoid unpleasant surprises. Adjust the band tighter than with a strapped model, the skin should be marked for a few minutes after removal. Check the fit by raising your arms before heading out, as this is the movement that can make the bandeau slip down. And opt for models with removable straps, which can be transformed into a standard bra for the rest of the time and make the purchase worthwhile.
