I didn't realize Laura Ashley still made dresses (I was still thinking of them as your go-to for floral tissue-box covers) but hey, here's one, and it's lovely. Big pockets! Cap sleeves! Blue flowers!
I didn't check if they ship to the US, and it's on the expensive side in pounds anyway (I always want to write "pounds sterling" — I'm sure there's a difference, but I've never been enlightened as to what that difference is).
Someone very nice sent me this link. I can't find the email now. Take credit in the comments, please!
