A. Under $50
B. Dressy enough for a wedding, while still being versatile for mixing and matching within her wardrobe once the wedding is over
C. Accommodating for her new, but growing baby bump
She knew she felt feminine and pretty in A-line or full skirts, plus those are easy to pull over a bump, so that was mostly where I started. I was just going to send her all these cute skirts I found, but I figured you all might be interested as well, so here is my rainbow of options for your browsing pleasure (be sure and click the little arrow to the right to see the few on the next page).
All are under $50 and include free shipping and returns--just click on the images that catch your eye and pair them with a bold necklace like this one, this one, or my personal fave, here, to take it up a dressy notch :)
