Smooth microfiber cups give this black underwire bra a clean profile under thin t-shirts and dark knitwear. The front clasp lets you slip it on without twisting around. We built the racerback cut to anchor your straps firmly so they stay off your shoulder edge all day.

How this one is put together

Front hook clasp
The center-front closure clicks shut easily, which helps if reaching behind your back is difficult. It sits flat between the breasts and keeps the gore stable under close-fitting tops.
Racerback geometry
We angle the back straps inward to clear your shoulder blades completely. The cut stops straps from sliding down your arms while distributing the weight of a full bust evenly across your upper back.
Unlined underwire cups
The molded single-ply cups follow your natural curve without added foam padding. A sturdy underwire encases full breast tissue to prevent spillage at the top and sides.
Smooth black finish
Deep black fabric provides solid coverage and will not show through darker tops. The soft, unseamed cup surface rests quietly against sensitive skin for long hours of wear.

Getting the size right

Take a snug under bust measurement on a full exhale, then an over bust measurement with the tape resting. The gap between the two sets your cup letter.

Sister sizing works here too: if the band is tight, move up a band and down a cup. How that works.
