I don't need any more work out wear, but this cycling shirt is too cute to pass up. I love the open back because every other workout shirt I have has a racer back and this gives me some sun in a spot that never gets any, plus I have some awesome back tattoos that you can see now.I ordered a size M and L and ended up keeping the Medium which seemed to fit better. I wear a bra size 34D and my measurements are 37-29-39. With the adjustable inner bra I am able to go without a bra, although only for cycling. For something more high impact I would add a sports bra.The back pockets are great and roomy enough. This is by far the cutest cycling shirt that I own. I also purchased the Sugar Syphony shorts in the matching Blackberry color and I'm very pleased with those as well. Now I have a cycling outfit that is both cute and functional. I'm very pleased with my purchase, the quality of the merchandise, the price and customer service of Amazon.
