Birthday outfits, makeup or hair?

Hi. So my birthday is on Sunday and I need some outfits, hair, and makeup for the following events.

1. So on Sunday I'm not really doing anything special. I'm going to church as usual (u can wear whatever u want, just so u know), and then I'm going out for dinner with my family.

2. The next day, Monday, I have school and me and my friends are celebrating my birthday at lunch (they're bringing me cake and stuff :D). And it's the day after my birthday so I want to look nice :)

3. The next weekend, I'm hanging out with my friends, basically for my birthday, we are going shopping and then going to a restaurant, the cheesecake factory.

Thanks! I'm turning 15 btw!
