Bra Fitting Guide


Around 80% of women wear the wrong bra size. Getting the fit right is so essential for comfort, support and confidence - did you know a well fitting bra improves your posture and figure in an instant


How to Measure Yourself at Home




Ideally wear the best fitting unpadded bra that you have. Measure around the rib cage, under the bust. The tape should be pulled firm around the body. Ensure tape is parallel to the floor all the way round. This is the underband measurement.


Cup Size


Measure over the fullest part of the bust. Ensure tape is parallel to the floor and not twisted.

Subtract the underband measurement from the over bust measurement to ascertain the cup size.


If the measurement is half an inch then round down to the nearest inch.

Tips for finding the best fitting bra


The band should feel firm and supportive, as well as being horizontal across the body, being the same level as the front of the bra. The hook and eye should be fastened on the loosest hook, ensuring you can fit two fingers underneath it.


The Underband


If the underband ‘rides up’ it is too big. If the underband ‘digs in’ it is too small.


The Cups


The breast should be fully encased within the cups. The cup should offer good support and forward projection, creating a smooth silhouette. If the cups are wrinkling and loose offering no support, it is too big and if the breast is spilling over at the neckline and underarm, it is too small. If the underwires are not sitting flat against the chest the cup size is too small.


The Straps

Straps should lie flat on the shoulders, not slip down or leave marks. Straps help balance the weight of the breast, rather than provide support and uplift; this is generated from the underband.



Centre front sits flat against the body. The breast should be completely encased in the underwire, which should be following the natural crease of the breast.
