To be honest I don't see the point in adding more underwear. We only ever see it in CAS. Unless of course your sim prefers sleeping in their underwear only. If added, this should really not have to be paid content, but rather a base game update.
I would not mind more sleepwear, but I also don't necessarily need more, because the game already offers a variety of tops/bottoms/dresses that can be used as realistic sleepwear (not jeans, blouses, jackets etc of course). I never only use the options from the sleepwear category.
I think we need other types of clothing more urgently. There is so much garbage clothing (excuse my language) from older packs that I never consider using. I roughly use 1/3 of all CAS clothing regularly. I think recent expansion packs did a great job at introducing more contemporary and especially realistic clothing. I want more of that! And please, give us a proper menswear kit that so many people have been asking for.
