How many outfits can a girl wear in one day?! If you're Hailey Baldwin, at least 4 or 5!

The model wore an adorable lime green gingham-checked ensemble with neon Off-White Nikes on the way in and a bright peach oversized blazer with baggy jeans and a cinched, belly-bearing top. Both cute!

Hailey's been ramping up visits to her stylist's showroom now that she and Justin Bieber have set their wedding date for Sept. 30. Obviously there are lots of fashion moments that'll happen - travel to South Carolina, rehearsal dinner, days of golf and being on the lake, of course the wedding dress and reception dress and then the day after. So much to think about!

Meanwhile, Hailey and bestie Kendall Jenner were seen boarding a private jet just after these photos were shot -- believed to be on their way to Idaho's Gozzer Ranch where both ladies vacationed separately recently and where it's believed they're celebrating Hailey's bachelorette!
