If you have a local lingerie shop that does fittings, I strongly recommend going for a fitting. They will have sports bras as well as regular bras. Jump up and down in front of the mirror or run in place to check to excessive motion. If you can't find a good local shop, try Nordstroms and ask for a fitting.

It might cost a few dollars more to go to a local business, but for this kind of purchase the extra service is well worth the price. After you have one or two sports bras that you've been out running in that you know work well for you, you can shop for sales on the Internet.
