Unique Vintage Women's Alice Swim Skirt

According to the size chart, the size I chose should have been a little big. In reality, the bottoms are WAY too small. An exchange is not accepted, so I’m expected to pay for a second pair of bottoms when the first pair was only bought based off of an inaccurate size chart? How is that my fault?

I've ordered the top for this THREE times with no right fit. I never order anything without checking the sizing chart AND outside comments on their sizing. But shame on me for only thinking it's worth it during final sale right? Bottoms were the same I just gave up until I got the top right l after practically falling out. The fact that IF I got it right I would've sized down 2 in the top (not even from what I normally order, just again off their size chart) and sized up one in the bottoms.

The skirt did not have the sanitary sticker at the bottom of the skirt and the bra top was not in the package and the bag it was packed in was dirty, none of this is good , the fabric was not good quality either
