I am SO happy with the material and fit! As my photo shows, all bras cut across my radiation fields, and that can be a problem. This bra is so soft and supportive, and it doesn’t rub my tender skin! I worried that the strap may rub, but not at all! I just taught a HIIT class with this on, and it felt great over my awkward tissue expanders, too :). This bra is definitely a big win for me!!
