Eloquii Flowy Shift Palm Tree Dress Travel Vacation Sz 20

Reposhing this item I purchased from @practicalthrift. Loved it, but I'm ready to rotate for something new. Recently bought this, but it doesn't fit. I'm so sad because it's so cute! Here it is about to be springtime, and I have to re-sell! I'm 5'7", and the dress hits about 3 inches above my knee. It's a size 20 (UK size 24, I believe), but there is no stretch, so I think it would be more comfortable and flowy on a US 18. Dress is from Eloquii as posted. Open to offers, thank you!
