That's what I thought, but then I realised we're thinking Earth years.
Banebear - this is not the WrongPlanet website you're in need of!
How old are you, though?
In general, I'd recommend tidier and better fitting clothes that are in a style you like. I'd also recommend growing your hair out, seeing what happens, what you can do with it. Your overall vibe is 'utilitarian', suggesting clothes and hairstyle aren't important to you other than to keep comfortable. Which may well be the case, and in situations like this I'm torn between saying 'yeah, you'll have to change' and 'be who you are, because that's who you'll be to any girl that takes an interest in you. Just maybe smarten up a bit'.
Fortunately, it's quite possible to change to become more how we are. Better versions of ourselves. Life will change you anyway, so you may as well get in on the process.
But, I'm not a lady, and I'm not of your age group, so help yourself to a huge pinch of salt to go with this advice.
