My primary concerns in shopping for a sports bra were:
1. comfort (no pullovers, no racerbacks)
2. shape/no uni-boob
3. support
4. price (under $50)

I ordered 36 C & D and this bra fits great. It gives me good lift and support, with little to no uni-boob and no bounce (though so far only used working out on a Cybex Arc Trainer (much like an Elliptical). I love the color (ordered the blue), the fit, and the fact that i don't have to struggle to get it off and on. My last sports bra was a Moving Comfort pullover bra and it is very difficult to get out of--i almost put a shoulder out of joint with that thing; will never order another pullover bra--ever! I also had a Lily of France underwire sports bra that was comfortable but it leaves me looking flat (henceforth i will stick to companies that specialize only in sports bras, not ones whose primary business is everyday bras). Another good thing with the Luna bra is i didn't notice any see-through (while wearing cotton t-shirt). I would definitely recommend this bra and anticipate buying more in the future.

UPDATE:  ABOUT 2 YEARS AFTER BUYING THIS BRA I WAS SORRY I PURCHASED IT. THE MATERIAL DOES NOT SOAK UP MY SWEAT AND DUE TO FRICTION AND BACTERIA IN SWEAT, WELL, IT CAUSED ME TO DEVELOP A LARGE, HARD CYST ON MY BACK RIGHT UNDERNEATH THE BAND. THE CYST THEN BECAME INFECTED AND HAD TO BE SURGICALLY EXCIZED. I HAVE NEVER HAD THIS PROBLEM WITH OTHER SPORTS BRAS, ALTHOUGH I HAVE NOT OWNED TOO MANY. I THINK I MIGHT HAVE OWNED A CHAMPION SPORTS BRA AT ONE TIME. MOSTLY I THINK IT IS DUE TO THE MATERIAL (and probably needs to be washed after every single workout). ON THE OTHER HAND, COTTON BRAS CAN GET SO SOAKED THAT YOU FEEL JUST AS GROSS WEARING THEM AS YOU DO WEARING MATERIAL SUCH AS THIS WHICH KEEPS THE BRA BASICALLY DRY BUT YOUR SKIN REMAINS WET BECAUSE NOTHING HAS BEEN SOAKED UP. I DON'T KNOW A SOLUTION TO THAT. UM..IF YOU ARE ABLE TO WASH THIS ITEM EVERY DAY OR A FEW TIMES A WEEK YOU PROBABLY WON'T HAVE TO WORRY ABOUT WHAT HAPPENED TO *ME*. I HAVE TWO OF THESE BRAS AND ALTERNATED WEARING THEM WHILE WAITING FOR ONE HANDWASHED BRA TO DRY (PROBABLY BETTER TO WASH IN MACHINE FOR BEST CLEANING).
I HAVE, HOWEVER, FOUND THE BRA RATHER UNCOMFORTABLE DUE TO AFOREMENTIONED REASONS AND NO REAL STRETCH IN THE BAND.
