Top runs big, pants run small but it's a set. I want my money back but I may have to keep. ugh. dont do it. It's also ribbed in texture

I was so excited for this set I bought two at one time. I read the reviews and believed if I sized down , I would get the oversized top but fitted shorts look like the model . Boy was I wrong and way off , these people on here lying this is the most unflattering set I ever put on. The shirt in lavender swallows me up like it’s a 1x and the black is too big and too small at the same time . The arms fit perfect but the rest of the shirt swallows me up . If I could return it I would. It doesn’t even look like a cute brunch set it looks like some thick pjs and that’s what I’m going to wear them as in the winter. Since I can’t return them . I’m pissed because I was so excited for this set to work out and it doesn’t buy at your own risk.
