I went to visit my mom today for mother's day, and she said she wanted to go to the mall to look at MOB dresses. She tried on a lot of stuff, and we figured we'd probably to to Macy's another day...until we ended up at the shop I bought my dress from.
Just as we were heading to the fitting room, I saw it. A top and skirt set in the most awesome shade of teal (my BMs are also in teal). It came down to two dresses, but in the end, my teal one won out.
Here are photos from the website:

I love this dress, and it's so much more flattering on my mom than a lot of the shapeless stuff I've seen. She's thin and not very curvy, so this fitted outfit looks better.
