I have used the Champion 6632 sports bra which does some compression. I am currently a 44 D and still have some bounce but not much and it is comfortable. Additionally, the sizes in the 6632 run very true. I usually wear one all day at work to protect the "girls" from boiler room episodes.
Thank you. I ended up getting the Moving Comfort Vixen A/B in extra large on Ebay for $22. Seems that these are either being discontinued or close because they are not easy to find online and nearly impossible in the sporting goods stores.
Anyway, it provides good support, but does not compress like the Champion does. In addition, the seam on the front is noticeable, but I doubt any normal human would be able to make the connection.
Hope this helps someone in the future.
Thanks.
