Three sub-requests: exchange, shipping query, and blocked return

Hi team, Hope you're well! I've got a few things to sort out if you don't mind: 1. I need to swap a dress for the next size up — my daughter's had a bit of a growth spurt and it's already too short on her. Same dress, just a bigger size would be great. 2. I placed another order a few days ago and haven't heard anything yet. Could you let me know where it's at and when I might expect it? 3. I also ordered a swimsuit (the Coral Cove One-Piece) but my daughter has decided she won't wear it. Would I be able to send that one back? Thanks so much for your help :) Aimee
