I was very careful to measure my glasses and use the chart. I was very pleased with a perfect fit. I love the case. The glitter does not rub off. It is just as described. I felt conflicted about spending so much on a case just to have some sparkle when I could have spent much less on a basic case.  When the case arrived I no longer felt that way. The sparkle is fabulous and I am thrilled with my decision. I ordered another in blue!
