I've tried more supportive bralettes, but this one works fine. I think the cup material is probably a little too stretchy. Some stretch in a bralette is always good, but this gives a little too much. However, it still gets the job done well enough and is so comfortable that I may even order more if this one holds up after a few wears. I am a 34F (34DDD), and I ordered the M/L, even though in shirts I usually wear a L/XL. I think the M/L in this was the right fit for me, though.
