Forget the old days of starching and ironing collars to make them look lifted and fancy. I have this because ties can be too much for many business casual occasions. But if I don't button the top button of my shirt and don't put on a tie, collars can look dull and flimsy. With this collar stopper, I don't have to worry about looking messy when wearing a trendy blazer. Try it - it works on casual short sleeve shirts too! First impressions matter, so if you want a relaxed, professional look, this is a must. Paired with a corset that fits neatly into your shirt, you're ready to win!
