I love collared shirts with tabs instead of buttons, but I'm not a fan of the plastic tabs they usually come with. I ordered these corsets - be sure to measure them against your shirt and order the correct size(s) - and they arrived in two days. They are exactly as advertised and work much better than the flimsy plastic legs. I take them out before I wash shirts, but it's okay if you forget them and leave them. They're stainless steel, so they should never rust.
