A 34F bra fits a 34 inch underband with a seven inch difference between your underbust and the fullest part of your bust. It is one of the most popular fuller cup sizes in the UK, so the choice is wide and the job is picking the right shape rather than tracking down stock.
Our 34F bras are led by Fantasie and Panache, in full cup, balcony, side support and sports styles, with most shapes in black and white. If the band rides up, your sister size is 32FF. If it digs in, 36E holds the same cup volume on a bigger band.
Full Cup and Side Support in a 34F
A full cup is the safest first choice at a seven inch differential, with the most coverage and the most even lift. Fantasie Belle and Speciality are the full cup workhorses here. Fantasie Illusion and Fusion add side support for a narrower, rounder profile, and the Panache Tango balconette gives more lift with a lower neckline.
Black and White 34F Bras
Fantasie Speciality, Illusion, Belle and Fusion all come in a black 34F bra and a white 34F bra, as does the Panache Tango. Royce Grace is a non wired option in white for softer support.
34F Sports Bras
For running or the gym, an underwired encapsulation sports bra holds a 34F far steadier than a compression crop. The Shock Absorber D+ Max Support and Panache Sport Power both cut this size.
Checking Your 34F Fit
The band should feel firm on the loosest hook and sit level across your back, with the centre front flat against your chest. If the cups overflow, try 34FF. If they gape, try 34E. Our fitting guide and bra size calculator will confirm it before you order.
