RUVI Fit Tip
Between sizes?
♡ Choose the smaller size if you prefer a closer cup fit and more supportive second-skin feel.
♡ Choose the larger size if you prefer extra room, more cup coverage, or a softer everyday fit.
Because every body is beautifully different, your perfect RUVI fit depends on both your measurements and how you love your bra to feel.
Founder Fit Note
I’m usually a UK size 10 with a 32 inch underbust and 36 inch bust, placing me between S and M in RUVI.
After testing both sizes, I found S gives me my preferred closer cup fit, while M gives a softer and more relaxed feel. I personally wear S with an extender for extra band comfort.
