Rubie's 881567 Nightmare On Elm Street Deluxe Freddy Sweater Costume T-Shirt, Striped, red, Talla nica

Hows the quality?

I wear medium shirts but large jackets should I get a standard size?

How much bigger is the ex large from the standard from the standard? the standard i bought fits perfect but a lil tight like a muscle shirt!

Would xl size fit like a 3xl or 4x? Also what kind of material is the sweater?
