I've lost a bit of weight lately, and been wearing more 36DD than my old size of 38DD in most brands.  Given the reviews recommending this runs small, I ordered the larger 38DD size.  I really should have gone with the smaller size, as the 38DD just feel a tad loose and I jiggle more than I like just walking across the room.  Unfortunately, I've already worn it too much (and took the tags off), so no return for me.  Oh well, risk I run living somewhere far away from anywhere I could possibly try sports bras on at in person.

I'll probably keep it around and use it for non-sports and lower impact related wear, and try again after my weight has stabilized and I know what my new size will be.  Everything else on this bra feels like it's top notch!
