LHELBIE T-shirt Different Material This T-shirt is made of polyester, which feels cool and comfortable. The sleeves can be tightened, allowing you to change the silhouette to your liking. Thanks to the back panel, it makes you look slimmer. My tastes changed before I could wear it much. I hope it finds someone who needs it. ✦I am also selling items from Graniph and other brands. I will do my best to offer a discount for combined shipping.
