The Vanderpump Rules Ladies Share Beauty Advice for Their Teen Selves

Brittany Cartwright and Jax Taylor keep breaking out the formal attire, and they're nailing it every time. First, the Vanderpump Rules couple coordinated in spectacular fashion at the Kentucky Derby, and this past weekend they got all dressed up for Jax's sister's wedding day. Not only that, Brittany wore a stunning bridesmaid dress to join in the bridal party.

How to Watch

Watch Vanderpump Rules on Peacock and the Bravo app.

The couple spent a few days hanging in Jax's home state of Michigan, doing outdoorsy things like boating before the big wedding festivities, but they definitely clean up nicely. Just check out a few photo from Brittany's Instagram account with her in her bridesmaid best. She's been killing her fitness goals, and this deep oxblood shade is definitely her color.

I love this girl right here! Congratulations @jennylynn1884 & @patrick2point0 this day has been absolutely amazing and I am so honored to be a part of it!! Love you guys!! ðð

Brittany also posted photos on her Instagram Stories to document the day. Here's Brittany with her fellow bridesmaid and the bride, with all of them looking radiant:

This photo gives us a full-length look at the silhouette of her gorgeous bridesmaid dress — but the caption here is totally Brittany. "No pit stains for this bridesmaid," Brittany wrote, with her method for getting rid of underarm sweat. OK, she really is an open book with her fans.
