Transformation!

Shoujo. A nerd in the past, he decided to ask a cool guy to help him transform into a super cool and handsome guy!

Shoujo. Revolves around a girl who is seen as nice during school but at night her school transforms into a place where people's true personalities show. The student council wears big glasses during the day, but once he takes them off he is very handsome.

Shoujo. Small fat unpopular high schooler can turn into a very handsome high schooler with the help of the powers of a magical king who got turned into a dog and is cursed.

Shoujo. Chubby guy who this girl decided to make into looking like a tall skinny famous actor to get revenge on her boyfriend for dumping/cheating on her.

Shoujo. Guy changes into a girl. Like, scientifically.

Shoujo. Sullen looking boy, outside of school, is actually found to have many piercings and tattoos. He he's a haircut later in which makes him look cute.

Shoujo. She lives in an all-girls apartment and is a NEET/otaku(?). Well anyway the cookie crumbles and she designs clothes and her friend (who is a boy) is able to dress her up and she looks really pretty.

Shoujo. A bit obvious, lol, but she chooses to transform into a pretty girl. And the guy chooses to wear ugly glasses. An okay Shoujo manga, but there's some potential love interest like every arc.

Shoujo. It's the girl who has a transformation from fat to skinny. She changes because she spent a whole week crying about her favorite anime boy so much that she lost weight AND her bad eyesight. Then the 4 most popular guys get interested in her at the same time =_=;

Shoujo. Girl changes hair, but it is not to make her appearance look cute or anything.
