For a muscular man, a slightly elastic T-shirt, half sleeves, various T-shirts, jeans, casual pants and a pair of shoes suitable for the occasion are enough. If you are in good shape, big and stylish, you can wear tight clothes without wearing tight clothes. Don't wear close-fitting clothes, otherwise going out will be like a decoration. But there are conditions. If three or five people of the same size walk down the street in tight clothes, it will be a landscape.
