The cut muscle shirt thread

I got a couple in London a couple of years ago at a gay shop in Soho. I chose the stretchy tight-fitting ones ... The other is cut a different way so that it exposes the nipples. Wearing this one, along with my nipple bars or rings, and skintight jeans that show off my equipment — it's an awesome turn-on and gets a lot of attention both at parties and the sex shop where I work
Did the customers ask to buy one of the same?
