The Pretty Price Check: Your Friday round-up of what we paid for beauty last week.

• 30: How old I’ll be on my next birthday.

• April 30th: Aforementioned next birthday. (I like flowers. And shoes.)

• 30DaysofBeauty: A 30-day Twitter challenge happening this month. The goal is to tweet #imbeautifulbecause every day for 30 days.

Okay, so it’s eight days in and I’m a little late to the party. But coming up with 30 reasons why I’m beautiful seems like a fine way to celebrate turning 30 — especially since our youth-obsessed culture loves to tell us that women get less beautiful as we age. Which is just bananas, of course.

You can join in too!

First, consider making a donation because the founders of 30DaysofBeauty are using their 30 day challenge to raise money for To Write Love On Her Arms, a cause that is dedicated to helping those struggling with depression, addiction, self-injury and suicide.

Second, let’s all tweet #imbeautifulbecause every day for the whole month! So much fun! Even if you aren’t turning 30 on the 30th in less than 30 days like me. (I’m excited about it, in case you can’t tell.)
