Take a deep breath

Don't tell your wife, "neither one of us looks like we did when we were younger". When she asks if you think this skirt makes her butt look big, either lie or be silent. It's the only way for there to be peace in the kingdom. Trust me, your wife knows she doesn't look like she did on your wedding day, what she's looking for is conformation that you haven't noticed because you love her no matter what.
