Whats wrong with these undies?

I recently bought new undies n because they were a brand that seems to have smaller sizing and in the past I never bothered buying so thought I'd play it safe n buy 16/18. Put them on that night n was complaining to my husband about their lack of quality. What's wrong with them? he asked. I said the elastic is stuffed already and he looked at me with strange little smile on his face n said... Kim, they not stuffed u duffer... They are too big. Wow I am not used to having that thought. I've kept them tho n wear them, baggy bum and all! They make me smile! Next undies shop is going to b in one of those little fancy places ; )
