If you need fitting into a run bra, Sweaty Betty does it and are very professional.
Also what some people don't know when try on bras, when you go down in the band width, you go up in a cup size. Hopefully this will help you find your size;)
I wear Sweaty Betty all sport shorts http://www.sweatybetty.com/all-sport-short-produw002_apricot/ I will not run in anything else now. they are high waisted, sweat wicking and very comfortable! Kx
