I would have given it 5 stars but I still get some bouncing.  I'm a 38D and used to wear Champion bras.  They are hard to put on, extremely uncomfortable, and Champion has issues with their sizing.  BUT, I did like the price so I tolerated them for a long time.  I saw Moving Comfort at my local running store and read that they're supposed to be the Cadillac of sports bras.  Amazon has absolutely the best prices on this line.  I was skeptical when I tried it on because it is, without question, the most comfortable sports bra I've ever worn.  It supports without the strangling compression of many sports bras.  I still get a little bounce (I don't think there's a sports bra out there that can eliminate it altogether) but I'm willing to trade a little bounce for the superb comfort level of Moving Comfort bras.  The Fiona is great.  I might give the Maia a whirl next time.  UPDATE: I lost about 10 pounds and bought another Fiona in a 38C and strangely it is actually BIGGER than the 38D.  It works after adjusting but I think the quality has gone down a bit.  I get more bounce and feel like I need to wear a regular bra underneath this Fiona in order to get the same support as before.
