Now a days the Iowa Hawkeyes Team Big Ten Champions Shirt moreover I love this line between formal wear and casual wear are blurred. But in the olden days ,T- shirts were worn strictly in a casual occassion and Shirts were worn in a proper formal setting and hence would be accompanied by suspenders followed by a waist coat and a formal coat on top. This could result in an uncomfortable wearing. It was only quite recently say later 90s that the shift to more casual work wear came about It goes both ways; we don’t want men dictating how we dress, and have no right dictating to them. If you don’t feel comfortable looking at a man’s bare chest, I suggest you stop looking. I am a student of a commerce college which allows Polo and Collar shirts and t-shirts but no round neck or v neck t-shirts. Personally , I feel round neck t-shirts are a bit child like to wear. It is good for in-house wear or beaches or holiday but not in colleges. On the other hand polo t-shirts look more mature and cool to me.
