Prepare to Add Hailey Baldwin's Pearly White Nail Polish to Your Wedding Pinterest Board

Hey, have you heard? Hailey Baldwin and Justin Bieber are getting married. No, no — they're getting married again, in public, with all the bells and whistles you'd expect from a normal-person wedding. (Um, kind of.) There was a bachelorette party! Rehearsal dinner! Celebrity guests! Photo sessions on a yacht!

Anyway, the rehearsal dinner took place in South Carolina on Sept. 29, and it was all whimsical and gorgeous and every other thing you'd expect from a couple with a joint net worth of $268 million. But zoom in on the photos, and you'll notice she was also wearing a pearlescent white manicure to match her Jimmy Choo strappy sandals and custom-made Vivienne Westwood minidress. As one does.

Of course, it's not entirely surprising that Baldwin chose an alabaster nail polish color for the occasion (spoiler alert: white is a big theme at weddings), but it is a smart move, given that the shade holds a lot of postnuptials potential. According to NYC-based manicurist and founder of her eponymous brand Jin Soon Choi, white nail polish — particularly one with an iridescent finish, like Baldwin's — is the perfect Fall color. "The pearl element adds an elegant dimension that is ideal for ushering in the new season, when more variation on your nails is needed," she said.

Ushering in a new season or a lifelong partnership, no matter — all we know is copping her all-white look becomes a lot easier (read: less money) when we're talking about nail polish.
