Bra sizes are just a guideline.

One of the most common things, after "I hate bra shopping!" is "My size is..."

After years of fitting I have found that one body is not defined by a specific size as the bra industry has not regulated the sizing or measurements of actual bras.  While there are commonalities within brands even a style or colour change will have an effect on the size combination required. There are times when a 34F will have a larger/longer band than a 36DD, even in similar styles and fabrics.

The key is to keep an open mind, avoid getting hung up on the number or letter, know the fitter has an in-depth knowledge of bras and how each style fits different bodies.


Three key fitting guidelines that make the size of the bra irrelevant:

1. The underwires fit snuggly, like a glove, at the crease between body and breast. No spaces, no skin on skin, no folding and smooshing. Avoid the coconuts on a string effect. If the underwires do not fit snuggly at the crease DO NOT buy the bra. No matter what other elements you like. Another size combination or style will work better so keep looking. You deserve the comfort and support of a correct fit.

2. The band is snug, can only be pulled an inch away from the body at the back, and parallel to the floor. Wider bands are more secure, stay snug longer and smoosh back flesh less. If the band rides up it is too big.

3. There is enough fabric in the cup to encase all breast tissue and have a smooth transition from bra to body. This includes the side boob. This must be encased in the wires as well.

Sizes have changed. I lined up a Chantelle 166 in 34D, which has been around for 20 years or more, and a Fantasie Deco 1554 in a 28FF, which is a new style, the bands and cups are the same.
