Wide leg flare jeans

Brand new with tags. Bought from a boutique and not able to return. High waisted, 5 button fly, 100% cotton. Per the suggestion of the boutique I sized up to a 3 to fit like a 0/25, 34” inseam. Does fit like a 0/25 just not flattering on my body type the way I’d like! Paid 65 with tax and shipping.
