Bra Type
Strapless Bras
A strapless bra is built to stay in place with no strap support at all, which means the band has to do all the work a band and straps would normally share.
Construction
Bands are firmer than usual, often boned for extra structure, and lined with a grippy material at the top and bottom edges to help prevent slipping.
Common fit challenge
Any band looseness that a strap might otherwise mask on a standard bra becomes immediately obvious here. A strapless bra that slips is very often a band-size or band-firmness issue, not a cup one.
What to check
- The band-only test (worn backwards and upside down) is especially informative for this style, since there are no straps to compensate for a loose fit.
- If it slips, try a firmer band or one size down in band with the matching sister cup before assuming the style itself doesn't work for you.
