Shopping for bras online can be a little tricky, I would recommended going into one of our stores and getting fitted by our certified bra fitters, they will provide the easiest solution and they can direct you to the sizes or styles to look for online; but you can certainly try at home, just be prepared to try on more than one style or size that may not work.
First we need to determine your band size, be sure you’re wearing a well fitting, non-padded bra while measuring. With a measure tape wrap it around snugly your rib cage, just under your bust line. Then refer to the bra size chart linked in product page, just under the display sizes.
Since everyone's breasts are different in terms of shape (even between your own breasts), the most accurate way to determine your cup size is by using band bra size as a starting point. The cups are sized relative to the band, so if you were to try a smaller band size but keep the same cup size, the cups would be too small. For every band size you have dropped, you will need to increase the cups by one size or vice versa.
Best fit will have the band snug, secure and low on your back on the loosest hooks. The underwire should lay flat in the center, providing good separation and come all the way around, encircling all of your breast tissue to the sides. If wires tend to poke or hurt you, you're most likely wearing a cup size too small and the wires are resting on top of you breasts causing discomfort.
While it may take a few tries, our free shipping and returns should make it easy for you to try on a several styles and ensure you get the right fit! If you find you have more questions, you can always contact our customer service team or one of our stores and speak to one of our certified fit specialists.
Hope this helps and again I'd highly recommend making a trip to our stores, they will make the process simple and do all the hard work of understanding bra size and fit for you!
