So, I'm in a little bit of a predicament. my fiance wants to me help his mom find a dress for the wedding. The only thing is, she is quite overweight. I know we'll have difficulty finding something that fits and looks good. I have a decent relationship with her. We get along just fine, but we're not very close. Any suggestions or tips on how to handle the situation? I'm okay with helping her find a dress, but I want to be careful not to offend her and to be encouraging.
