Date with my secret crush?

I am bisexual and I have a friend who is a lesbian. She is one of my best friends but I’ve been crushing hard on here for a while now. She obviously doesn’t know.

Anyway, she invited me to go to the movies with her and one other friend. I know this isn’t really considered a ‘date’ but I kinda feel like it is a half date. If that makes sense.

I’m just trying to drop subtle hints that I like her and I think this could be a good opportunity.

Any ideas on what I should wear, say or do to tell her I like her?

Also we’re seeing Love Simon and I am SOOOOO EXCITED!!.....And nervous!
