Call me crazy, but I googled the material of the Skims Boyfriend Tee, and I found this Dupe on Amazon made by Fisher Finery. I confirmed my research by reading an article... I mean, by watching a TikTok by the creator Badgalru_ru who had also found the same brand of comfty tee's. I 1000% recommend buying these t-shirts for $13-30 instead of one for $45! They are made of the same material and feel exactly the same. I have the tee in size large. It covers my bottom, and has such a nice slouchy fit- I get compliments every time I wear it.
