Hi, I am new in buying suit.

Want to ask, is wearing a slim fit suit meant to limit the arm movements? Or the correct 1 is after wearing slim fit suit the arm still can go 360 without pulling the suit?

I had tried the slim fit suit in Padini and it suits me well, the only problem is I cant raise my arms because the suit is pulling. But if I go 1 size bigger then it doesn't looks fit..
