I was searching for a large strapless bra on the net when I stumbled upon Uniquely Woman. It lists hard to find clothing in a variety of categories - in my case plus size, but it also does petites, etc. - brings everything together. I also noticed it has a section on suppliers of post-mastectomy wear which I think is great. It has hundreds of suppliers listed (particularly in the plus size category) and articles on what to wear if...etc. although I didn't really have a close look at these. However, I did manage to find 3 or 4 potential suppliers of my elusive large, strapless bra which I will now be contracting!
The site is worth a vist though and I will go back when I want some more plus size items....(to go with my new bra hopefully!)
