Use this guide to find your perfect fit from the B Free range. Women's bodies come in all different shapes and sizes so not everyone will sit perfectly within one size. To accommodate for this, most of the B Free range is knitted on seamless Italian machinery that creates a soft and stretchy fabric with easy fit flexi-sizing. As a general guide, we recommend ordering tops & slips according to your bust size, shapewear according to your hip size, and underwear according to your hip size. Note that this can vary depending on your body shape and personal preference.
Shapewear, Underwear, Tops & Slips Measurements
This size guide gives you the body measurements for standard Australian numerical sizes. Once you find your standard AU size, look on each B Free product to find your corresponding B Free size.
Note that the bust measurement is only relevant to tops and slips, and the thigh circumference is only relevant for the anti-chafing midi shorts.

We do our best to make the fitting experience as simple as possible, but we understand that when shopping online you might not always get the perfect size and fit for you. This is why we allow 45 day returns on eligible products as per our returns policy.
Please note: You may find small variations in sizing between dye batches and colours. In general darker colours may be slightly denser and firmer, and lighter colours more relaxed. Due to the seamless nature of our garments these differences are not usually noticeable when worn on the body.
Seamless stretch garments will appear considerably larger after trying on compared to new unworn garments. This does not affect the fit or quality of the item and is the nature of circular seamless technology.
