The prettiest tooth fairy of them all! Lauren Conrad got in the Halloween spirit this year by once again making her very own costume. On Oct. 31, the newly engaged Paper Crown fashion designer revealed how she created her pale blue tooth fairy costume via

"Every Halloween, I have so much fun making my own costumes from scratch. This year I decided to dress up as the tooth fairy," the 27-year-old bestselling author wrote alongside pictures of the hand-making process. "I bought all of my supplies the week before (including yards and yards of tulle) and spent a few hours crafting my costume on a dress form. I was quite pleased with the end result!" 

PHOTOS: Lauren's best hairstyles ever!

Indeed, the Hills alum shared a final picture on the blog wearing the finished product. Conrad wore a nude slip for the costume and used tulle fabric for wings. She also swept her blonde locks up in a bun and carried a tooth bag for the photo-op. (Another photo also gave a close-up look at her stunning new engagement ring!)

This isn't the first time the former Laguna Beach star revealed her fairy outfit. Last week, the Sweet Little Lies author debuted the costume while attending Matthew Morrison's Halloween party at Hollywood hotspot Warwick on Oct. 26 with her fiance William Tell.

"They sat in a booth in the back with friends most of the time," an insider revealed to Us Weekly about the couple's time at the party. "She was showing off her ring but there was no wedding talk."

Conrad announced she was engaged to the 33-year-old Something Corporate rocker turned law student via Twitter on Oct. 13. "I am very excited to share with you guys that William and I got engaged over the weekend," she wrote at the time. "I am beyond thrilled! Get ready for lots more wedding content here on as we begin the planning process."
