It is “Can I afford NOT to have my makeup professionally done?”
Yes. Yes you can. You do it EVERY OTHER DAY.
Well, no. Not everyone does.
People don't take pictures of me every other day, so my lack of make up really doesn't matter. I also don't wear an incredibly formal gown every other day, so I don't need to look made up.
I never wear makeup for regular wear. My make up collection consists of cheap mascara, black eyeliner with glitter in it, bright blue eye shadow, bright pink blush, and corvette red lipstick for ice skating competitions. I'd look like a freak if I wore that at my wedding.
So I had my make up professionally done for my wedding (and my hair, since my normal hair style is a pony tail- I don't even own a blow dryer). She did a great job and it didn't cost that much. It would have cost more to have to buy all the stuff I needed, not to mention to learn to apply it so I didn't look like a clown, since clown/performance make up is the only way I've ever worn it. I don't know how to do normal make up. It seems like a lot of work to look like you didn't do any work at all.
For my sister's wedding I had my make up done and I think they made me look too pale, so the photos bother me. But for my wedding, it was definitely worth it. I look WAY better in photos than if I had not worn make up at all. (For other picture taking occasions I put on the mascara, but nothing else. Normal days are make up free)
