A 42F bra fits a 42 inch underband with a seven inch difference between your underbust and the fullest part of your bust. At a 42 back the band is doing almost all of the lifting, so the depth and firmness of the underband matter more than anything else on the bra.
Our 42F bras come from Elomi, Fantasie, Panache, Goddess and Curvy Kate, in full cup, side support, non wired and sports styles. If the band rides up your back, your sister size is 40FF. If it digs in, 44E holds the same cup volume on a bigger band.
42F Sports Bras
Sports is the most searched for style in this size. An underwired encapsulation sports bra holds a 42F steady by separating and supporting each side, where a compression crop flattens the bust and puts the load on your shoulders. Elomi Energise and Curvy Kate Everymove both come in 42F and both use a wide, deep underband to do the work.
Everyday Support at a 42F
Full cup and side support styles are the reliable choices for daily wear at this size, with wide side wings and cushioned straps that stop the bra shifting through the day. Non wired 42F bras from Royce and Triumph give softer support for lounging or sleep.
Checking Your 42F Fit
The band should feel firm on the loosest hook and stay level across your back. If it rides up, the band is too big rather than the cups too small. If the cups overflow, try 42FF. If they gape, try 42E. Our fitting guide and bra size calculator will confirm it before you order.
