I have a pair of comfy old jeans (Levis) that seem to fit the same as they always have, except for a new problem...
The zip won't stay up.
Is it because
A) They're old jeans, and the zippers just don't work well any more on old jeans, or
B) Because although I haven't gained hardly any weight over the years, my shape is changing as I get older and my tummy is fatter.
If B), would getting fitter make the jeans fit better, or should I give up on them?
TIA.
