Is this intj seeking attention or does she want me to try again?

Shot my shot a female intj. She curved me and said she sees me as a friend.

Strange bit: She’s normally very lax in her appearance. Never seen her dress well once, but the next time she sees me after rejecting me she’s as dolled up as can be. Great dress, lots of makeup. Seemed a bit nervous around me, and was less talkative and outgoing than she normally is.

No one else was around that she’s interested in.

Any idea for the unexpected behavior post curving me?
