I need help!

Okay so I am a moh in a wedding in 5 weeks. This is my first time in a wedding. I’m not a very girly girl and don’t really know how to prep myself for the wedding. I’m assuming to get my nails done and re-dye my hair but like what are all the things I should do? It in Florida and I live in new York so I know I should stock up on sunscreen. Do I go get waxed or is just shaving fine? Do I tan? Like I’m so lost on getting myself to look my best for my best friends day. She’s constantly making sure I’m “getting prepped and ready” and I’ve just been agreeing with her. Help 😩😩😩
