Katie,
Love the story. So I am lucky to have accepting, loving wife. And when we shop together, sometimes she will buy something for me. But I think she is concerned with SA or others knowing it's for me (I'm much taller). She doesn't want to embarrass me, and I think she's concerned we might run into someone either of us knows. The solution is to shop out of town, where risk is much less. I have shopped by myself out of town and openly told the SA it's for me. You have advantage being similar sizes. Your hubby is very lucky
