I'm going to call a co-worker's wife ugly.
Why would you call your co-worker's wife ugly?
Her taste in fashion is terrible and she looks awful.
You shouldn't call anyone ugly. Everyone is special in their own way and you don't want to go around hurting people's feeling like that.
She should know how she looks to others, I'm not the only one that thinks she looks ugly.
Everyone has their own style and taste and it makes them unique. You should try to respect her and what she wants to wear. Think about how you would feel if the situation was reversed.
