Avril ribbed cotton modal short sleeve u neck - PerfectWhiteTee [BRAND NEW]

Heather Grey, size medium u-neck ribbed T-Shirt from PerfectWhiteTee. Brand new, never been worn. Runs a size small and I didn’t realize before ordering. I was unable to get the company to reply to do an exchange. From the website: “Cut in our slinky cotton rib, this new tee is everything you need to build your wardrobe this fall. a blend of cotton/spandex allows the fabric to hug the right places while allowing a natural drape. it truly takes you from day to night. please note for heather grey: due to the unique cotton rayon blend used to construct our heather grey rib, we recommend sizing up one size. choose your true size for white + true black”
