Lady Grace
I just wanted to post a follow up to my post from the other day.
I went to Lady Grace in Tyngsboro, MA. The women there are wonderful. They measured and fitted me for a bra (and as I had suspected, I went down from a 38DD to a 36D). I ended up with this bra:

In nude. Tried it on today with my dress, and its perfect. The bra is extremely comfortable and supportive, and its not so long that it feels uncomfortable near your hips, like some of the others I tried on. It added enough extra padding to my dress so that my dress isn't as loose as it was, though I definitely need to watch my weight. If I get even the slightest bit thinner, I will have problems keeping the dress up.
(The issue is that I am now running alot, and since I started running, I've gotten remarkably thinner, especially in my chest). I don't want to stop running, so I am honestly not sure how to keep from thinning out at all.
Anyway, just wanted to let you all know that Lady Grace is a good option for longline strapless bras.
