I'm 5'2, 106, 34D, short torso. All my sports bras
were 5-6 years old, definitely beyond their use, so I decided to try several MC styles in 34D or Medium: Luna, Juno, Jubralee, Fiona, Rebound Racer, Urban Xover and Vero. Most of these have favorable reviews. Here are my opinions. Luna was definitely out - cups did not fit well & overall it felt like a regular bra not a sports bra. I don't need another day bra - have plenty of great-fitting regular bras
(try Soma's - they are outstanding, best bras
ever!) Juno had good support, almost no movement, but the sides were too high & chafed my arms. I knew Juno would be difficult to get on/off from other reviews but once on, it felt & looked like a medieval instrument of torture, even moreso on my petite frame and short torso. Couldn't wait to extricate myself. Fiona was really disappointing - it's been their flagship bra for a long time and it looks old-school. The support seemed minimal, fabric thin, straps too bulky & overall just not that attractive. Jubralee was definitely a step up from Fiona & the best of these 4 that have the wide, 3-hook back strap, which is a pain & unattractive, probably because of my small frame. Jubralee had the most support, little movement, the sides were lower & didn't chafe, the straps are much thinner, softer & smoother, and it's comfortable. The only complaint is all the excess fabric on the inside of the cups, which is just weird. Other reviewers commented on the same. Maybe I need to try a C cup. It's a possible keeper but I wish it had cups like Juno & a smaller back strap. The Rebound Racer is a little hard to get on but fits much better than Juno for a racing style. Back strap is thinner, very good support/little movement, lower sides/no chafing. The straps seem a little bulky but overall this is a keeper. My absolute favorites are the Urban Xover and Vero. Both have thin straps, thin back straps, great support, no chafing, very little movement, great colors and a more modern style/feel. Plus Vero has convertible straps so you can make it a racer if you want. It's been a long time since I've worn a racer back style but Xover is so comfortable! Love these 2 and will order more colors!
