Blue Patterned Geometric Patchwork midi Dress

I purchased this dress online from Target. I have another one in green. They actually look exactly like the photos- color and shape. They’re super cute but the arms were a little tight for me (common problem for me and tops). Tied waist. Measurements are in the final photo. 100% Polyester. It matches the size of an 18. Chest: 42.1-44.9 inches Waist: 33.8 - 36.6 Hips: 44.9 - 47.6
