(Some of these things are not popular in general, some just not popular at BtN.)
I like preppy clothes. I can't help it-- I love pearls and polos and salmon colored shorts, polka dots, and monograms. No popped collars though!
I think kids are the best. Kids don't seem very popular here. I love them. I love spending my day taking care of kids.
Panty hose. I may be the only woman (or man) in the world that likes them, but I just feel so intact wearing them. Having psoriasis on my legs also makes hose desirable, but even before I had psoriasis I liked them.
Show tunes. People make fun of me all the time because I love show tunes, even cheesy ones. Love them!
Hats. I wear them quite frequently. It's not that people don't like
them per se, they just think I'm a little one off for wearing them. More people should wear hats!
Getting dressed up. Like on a daily basis. Everyone I work with wants to wear scrubs all the time, but I hate scrubs and will only wear them when I'm working overnight or in the ICU or ER. Otherwise I much prefer to dress up.
