Getting the Right Fit
Frequently Asked Questions
How do I measure my underbust?+
Measure snugly around your ribcage directly under your bust. If odd, round up to the next even number for your band size.
What if I am between sizes?+
Try sister sizes: same cup volume, different band. E.g. 34C = 36B = 32D in cup volume.
