If you are looking for a less expensive, but still super comfortable and supportive option - I have recently discovered the Dip brand at Fred Meyer, and the Sports Bras come in sizes to fit from xs to 4x and are $24-34. They are awesome! I bought one as a test - loved it so much I went back and bought 2 more. They also have other plus size athletic gear - I bought a pair of moisture wick leggings, but haven't got to really test them out yet.
