This is a picture explanation of how a personal fit at South Bay Boobology works:
1. First measurement is around your chest, under your breast
2. Second measurement is across your the widest part of your chest
3. The fitter shows you the available selection on our tablets
4. The fitter helps you put on the bra to ensure proper fit
Step 3 and 4 repeat until you have a comfortable bra that suits your needs.
