Hip seams don’t lay flat because it’s cut on a bias
"Looks great on the top but the hips have a weird bubble shape and seams won’t lay flat. Material is cut on a bias ( cheaply done to save money) so it is not possible to fix to perfection. Looking back on the model photos retrospectively, it is interesting to see that models’ arms are conveniently covering the hip seams in many photos. Save your money and buy something else."
