Recently got a new job, switched from everyday work to the shop, so I had to give up classic collar shirts. For the first few days I wore ironed stand-up collar shirts, but still got a very undesirable collar aesthetic. Just a flat and sad look, messy. Before I redesigned my entire wardrobe with button-down collars, I found this. They're a bit pricey (you can make it cheaper by ordering the stainless steel magnets and metal lanyard individually) but the beauty is that multiple sizes and pairs come in a handy case and you know they'll work. From day one I was immediately complimented and asked if I had a new shirt etc. Basically it gives any shirt a "button collar" look and in my opinion this is a MUST HAVE for a casual shop environment. It has saved me from having to buy all new shirts and has given me the opportunity when shopping for new shirts knowing that I can use these corsets and they will look great.
