Teen Mom 3's Mackenzie Douthit is gearing up for a big, off-white wedding to her baby daddy, Josh, and we couldn't be more excited! These two are tying the knot in just three months (right before their move to San Diego), and Mackenzie is in the thick of planning. In fact, she already bought her wedding dress (dreamy sigh!), and she's head-over-heels in love with it! 

"Why do I love my wedding dress?" Mackenzie tweeted on January 10. "Cause it make me look tall ;) it's like a optical Illusion."

There's no denying that Mackenzie is on the short side, but she has legs for days that definitely make her appear taller than she is. Either way, we're going to wager a guess that this gal's dress is a fit-and-flare (aka mermaid style), which are known for elongating the waist and torso.

In other news, we couldn't be more excited about this wedding, y'all! Especially if Mackenzie and Josh take tips from Leah Messer's wedding to Corey Simms. Camouflage tuxedos, guys. Make it happen.
