As you can imagine, I get this question a lot. And while there is no right answer for everyone, I can give you a few places I love, depending on your shopping preferences. 

For an Experience: 
Do you want to feel like Julia Roberts in Pretty Woman where all the sales people are doting on you, finding you the perfect sizes, and tell you what looks best? Make an appointment at Anna Bella Fine Lingerie in Alpharetta, GA. Yes, it's a bit of a drive, but take a friend and make a day of it in Atlanta. 

For Supporting Local Small Business: 
Located on Highway 58, Xcite Lingerie offers a variety of affordable options. 

For Convenience:
With the largest variety of sizes and colors to try on Adore Me and Victoria's Secret in Hamilton Place is a must-stop on any lingerie seeking mission. 

For Price:
I am a bit of an Amazon-holic, so my first stop for anything is always Amazon! But they surprisingly have a ton of great lingerie options (and make up about half of my client closet). I would take advantage of their great return policy and order a few different sizes, as some of the pieces tend to run small. Another great and affordable online option is Nasty Girl. 

My Favorite Online Boutiques: 
BlueBella
Journelle
Thistle and Spire

And they were a HUGE hit for our Valentine's Day sessions. But don't worry they aren't going anywhere. We currently have a black and Peach pair of angel wings that are just one of the many unique items I keep in my client closet for all my clients to enjoy during their session. So much of boudoir is about embracing a side of yourself you don't get to indulge in very often, so why not become a Victoria's Secret model! The second you slip these wings on it's impossible not to feel beautiful and glamorous !
