7 Pack Metal Collar Extenders (5 White, 2 Silver) Dress Shirt button Collar Extenders are Perfect for more Extra Breathing Room and fit Men or Women Dress Shirts

The product offers minimal expansion (about a half size) which was sufficient for one shirt and inadequate for most. Best to simply reposition button where practical. Thin wire guard over stretch loop was easily distorted. White is a less obvious color than silver.

I've used these before, and once they are on, they pinch from time to time when you move in your shirt. It's just not for me, but may be for others.

Sometimes my clothes shrink in the wash, sometimes they seem to shrink in the closet by themselves. Whatever the reason, this can save some shirts that get a bit tight in the neck. It is not as good as a well fitting garment, but it beats getting rid of a nice shirt.

I was excited to get this, but after just one use, the spring twisted just enough so that it pinches whenever I try to wear it now. I wound up new shirts instead and gave up trying to get this to work.

Perfect for huge overweight necks. Now I can still keep eating what ever I want & still button that dress shirt. When losing neck weight is not an option, look no further. LIFEHACK!

So....it does in fact expand the neck on the shirt, but in doing so your shirt looks like crap. The loop is elastic so it simply stretches open which causes a visible gap in your shirt...which is not hidden by the tie. The reality is if you simply need a looser neck, and dont care too much about how it looks, this is a great product. If you expect to also look "sharp", forget it....it will not happen with this product.

My husband can't do with out these. Keeps his collar from being too tight. We gave one to our preacher & he loved it too!

The problem is that the elastic band is difficult to get over the shirt button. Better to get the brass extenders that just slip on and off, rather than something that has to be finessed around the button.
