Upbra® Bra Fit Tips

 How do I know if the Upbra bra will work for me?

If you are able to take your hands and push your breasts together easily to create cleavage then the Upbra bra will work for you.
 Upbra Bra Fitting Tips    In between bra sizes?
For women who are in between sizes, Upbra’s flexibility and adjustability allows you to still get a great fit and amazing cleavage. Here’s how:
• If you find yourself in between 2 bras sizes (for example 34B and 36B), For an Upbra bra or bikini, we suggest going with the smaller band and the larger cup size. for this example above, that would mean choosing a 34C. It’s important for the band of the bra to fit snug around your body in order for the Upbra to work its best.
• If you normally find yourself between 2 cup sizes with the same band size, (for example 36A and 36B), we suggest going with the smaller of the two. The Upbra bra needs to fit snug in order for the bra to work properly and fit comfortably.
• If you have asymmetrical breasts (one breast larger than the other), we suggest going with the bra size that accommodates the larger breast. If there is any gapping/spacing within the cups for the smaller breast, you can adjust the bra using the cleavage control strap on the smaller breast's side further to close up any gaps or spacing.

     Can I try a different size if my size is out of stock?
Please do not order a size simply because your regular size is out of stock. Sometimes we are out of a certain size for a week but we will eventually get it, email you, and ship your backorder quickly.
