Zara long sleeve green peplum hem dress

Worn twice but the bodice is a bit tight fitting so I can’t zipper it up all the way. There are minor pills on the back (on the back close to the zipper and at the bottom on the peplum hem) that I’m not sure how they occurred Bc I wore very few times as noted above. They aren’t noticeable if you’re wearing the dress Zara size XS 0/2
