Work great! I love when my shirts look really stylish and these corsets keep my neatly pressed collars looking great all day long. I like the 2" and 2.5" sizes as they fit all my shirts. They are organized in the box and always ready to hand when I iron weekly and get ready for the work week. I can tuck the rest of the collar into the collar of any shirt right after ironing and all my shirts come out looking neat and ready to hand without fiddling with them.
