Fit Tips
What's my size? How to measure bra size?
We have two methods to determine what your Upbra bra/swim top size should be:

1. Bra Size Calculator:
With Upbra's bra calculator, there’s no hassle when it comes to finding the perfect fit for you. No measuring tapes, complicated calculations or convoluted bra size charts. Just answer a few simple questions about the bra that you currently wear. That’s it! Our algorithms use your answers to recommend the perfect Upbra bra size for you.

Please answer the following questions regarding the bra you are currently wearing and then press "Get Results" to determine what size you should get:


2. Upbra Bra Fitting App :
A new way to get your bra size measurements - we are currently testing a new bra fitting app. No need to use a measuring tape or even take photos of yourself in your bra. The Upbra Bra Fitting App gives you the ease and privacy without all the fuss. Just follow our step by step detailed instructions to measure yourself to the 3 graphs and select the measurement that best correspond to you and answer a few questions, that's it! The app will show you your best Upbra bra size. Right now it is available as an online utility for some smartphones (iPhone 5/6/7 & Galaxy 6/7). If you'd be interested in being one of our early testers, please click on the image below:

If you use the test app to determine your size, we will guarantee your fit. This means that if you order an Upbra bra in the size given to you by the app and for any reason it does not fit, 
we will reimburse you your return postage up to $9.95 USD for your return until you get the correct size fit.  

When you are wearing the correct size bra, there should be no spacing within the cups, and the back band should be at the loosest hook but feel snug. This is recommended because throughout the life span of the bra, the band is known to stretch out. When the band does stretch out, then you will be able to hook it on a tighter clasp.

Of course, if the size you receive does not work out for you, you can always send it back for a refund or exchange within 30 days from the date in which you received your original shipment. Items marked as Seconds/Slightly Imperfect Upbra® bras/swim are not eligible for a refund. For more information, click here.

If you are still not sure, please feel free to email us at and one of our Upbra® Bra Specialists will be glad to assist you with your order.  
               How do I know if the Upbra bra/swim top 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. And the hint is easily. If you have to significantly push your breasts together to try to achieve cleavage, then unfortunately, the Upbra bra/swim top will most likely not work for you.

Can I try a different size if my size is out of stock?
                   Do not order a size simply because your regular size is out of stock. The Upbra® Bras & Swim Tops will not fit you properly or give you the most dramatic results if you are wearing the wrong size.

                Special note for A cup sizes:
                    An A cup person should always wear an A cup.
