I hate wearing sports bras--they make my frequent workouts so frustrating bc I have to rip them off my sweaty body. This one goes on really comfortably and is only light compression. The bra part keeps everything in place, but the shirt part sits so nicely against my body, so it gives a really flattering figure despite being supportive. I'm a 34C and the small fits perfectly. I'm not sure if it'll stretch after a wash, but the bra portion seems to be made of normal, synthetic workout material so I doubt it! I plan to use this for yoga mostly, rather than running as the material is slightly thicker than I like for running/intense workouts.
