OHMIIGAWSHOHMIIGAWSH! I NEED SERIOUS STYLING TIPS FOR A DATE.

Okesh, I'm goin out with this buff boy that goes to my bruvvas secondary school and I've liked him for a long time. We're going for a walk in the park, but I think it's gonna be windy. I have bangs and shoulder length hair, do you know any simple hairstyles that I could do. Also, I'm planning on a sleevless turtleneck top thats white and a denim skater skirt. I'm gonna be wearing ugg boots and my wooly white tights underneath because I think it will be cold. I know this sounds cheesy but what if this outfit isn't sexy enogh, what if the wooly tights look weird, what if I stain my white top, what if I don't brng a cardi because I want to show off my top but get really cold? Do you think he will put his coat around me? AGHHH HELP-!
