This is an odd question, but here goes: My pants fit comfortably at the waist during the warm weather when I'm more active outdoors. Beginning in the Fall and throughout Winter, I gain a little weight every year, making my pants uncomfortably tight. By summer I've lost the winter weight. I've tried some different waist expander buttons and stretchy fabric but they all seem cheap though somewhat effective. Have any of you found a waist expander for that extra inch on the waist that is made well and works for you? (I realize that a belt covers up the waist expander and its cheap look and I don't want to buy two sets of the same trousers, one bigger in the waist for Fall and Winter.)
