A little behind-the-scenes from our upcoming styled shoot… ✨

Today was dress day!

I spent the morning at Vayda Jane Bridal selecting not one… not two… but THREE incredible gowns for our upcoming styled shoot.

And the sweetest part? Kaylynn (one of their Senior Sales Consultants) is going to be our model! We are SO excited to bring this vision to life together.

I absolutely love working with Vayda Jane and am so grateful to collaborate with vendors who love creativity and styled shoots just as much as I do.

More behind-the-scenes, vendor reveals, and sneak peeks coming soon ✨
