Size Purchased: M
Usual Size: S
I could have probably gotten a S and it would have fit fine, but went with a M as I was concerned about the reviews that said the shoulders and arms are tight (and I have a big ribcage, so this always concerns me as I have to wear XL sports bras under size S tops).
The dress fit well for me, but the mesh was a little big in the waist and hips, due to ordering the next size up.
That being said, the dress slays.
But here's the thing I didn't count on - this dress is heavy! It's made from SCUBA-type material for the stretch and weighs a good 4-5 lbs or so. Due to the thick material, and despite the mesh panels, it's hot to wear. I was sweating trying it on at the end of August!
That being said, it seems to of quality construction. The appliques do protrude a little on the sides of the profile, but they seem very well sewn on, so you want to make sure they don't get folded or pressed down the wrong way and stick up (either by storing improperly or having a seat belt bend one the wrong way while wearing it in a car). The mesh seems very strong as well.
