Japanese-themed Style Kei Clothes Gothic Hoodie

i order a size large in hopes to have it as oversized on me but when it arrvied the material is thin, the size is equivenlant to a M on me and when i try to email the company to ask to send it back they have not responded and what has felt like ignored me

Material was cheap, size was wrong, and learned afterwards that this product is also sold on Shein for only $15

Cheap no what it looks like
