It's my best friends' 40th next month. She's pretty glam and has one university aged child, I am much less glam and have primary school aged children. I'm grumpy and frumpy basically. My nails looks crap, my skin and hair are dry and my skincare routines are a bit patchy. I haven't seen a lot of our mutual friends since we were all young and fab and I want to give the vague impression that I've not changed much 
I'm going to restart 30 day shred to firm things up and really clean up my diet. I'm good with that kind of stuff but what do I do with my hair/face/nails? Should I get eyelash extensions? Do things with my eyebrows? Get gel nails? What can I do to make my skin look as good as it can with a month to spend?
Please help! :)
