I love Prana's yoga tops so thought I'd give they're casual wear a try. I usually wear a small but read some reviews about this being a little small fitting so I ordered a medium. I'm 128lbs, 36A and it fits fell. Fitted but not skin tight. I initially got the melon color and loved it so much that I ordered the blue/purple design. I layer them over a tank for warm up during yoga and they also look great with jeans, capri pants and skirts. Great spin on tie-dye if you're not sure about committing completely to Grateful Dead hippiness!!
