C-ZOFEK Women's US Size Chainsaw Man Makima Cosplay Costume Outfit with Tie (X-Large)

I am normally either a 14 or 16 in size. I got an XL and finally tried on the cosplay. It does not fit. I probably would have fitted the size 18. My fault, I should have tried it on beforehand and exchanged it. Maybe next year.My advice? Size up.
