I purchased the top in black med and it fits true to size. The only thing with this top is I wish it came with breast pads like many yoga tops do now, however their are slits if you have your own pads there is a place for them. I wear this top for yoga and it is extremely comfortable!
I love this tank top, it's soft, perfect support and length for yoga and has a cute keyhole opening and detail in the back! I'm usually a sz Med in tanks like this, it fits true to sz and got it on sale too! Thanks Moosejaw!
