Nordstroms calls me a 38DD but I do very well with 38D when it comes to Moving Comfort.

This is a great athletic bra...I use an alternative Moving Comfort model (Juno) for anything truly high impact such as running to really get the no-bounce.  This bra does allow for a bit more movement than I prefer for those activities.  However for every other workout this one has great support and is just enough more comfortable I prefer it (think TRX, elliptical, stationary biking).  I also wear it frequently as my everyday bra.

That said, I suspect it will do very well even for the higher impact sports for smaller cup sizes.

It's made of good materials and the workmanship is such that I've not had any trouble (and I've owned about 6 or 7 of them now).  The back strap has 3 size settings and the straps are easily adjustable which is very convenient.  In the higher sweat situations it also does a great job of wicking and staying comfortable.

One shopping tip for Amazon is if you notice that some style/size combos have Prime shipping this means that either Amazon is the vendor, or the seller uses Amazon's warehouses for keeping inventory.  This means that particular size/color will fall under the normal Amazon shipping scheme (Prime=free, or be eligible for super shipper savings).  If you aren't particular about color, just plug in your size and roll over the color options.  Some are just less costly in general, and the one I found was about half the base cost, including shipping.  A great way to get a super bra at a super deal.

HIGHLY RECOMMENDED!
