We have recently expanded our sizes offered to 13, to better serve all new mothers. If you have any suggestions, requests, comments or feedback - we would LOVE to hear from you!

We have been asked many times for sizes we don't currently offer, such as a 40K, for example. We will happily work out a tailored bra for you by having our factory match a larger top with a smaller band if you find that your size is not listed. We can also do the reverse with a bigger band and smaller cup (e.g. a 42B). This service is the same price (19.99 including free shipping) but it takes approximately 2 weeks door to door and these bras are non-refundable and non-exchangeable.
