Making a quick dress change before hitting the stage, Lauren Conrad participated in Cotton's 24 Hour Runway Show in Miami, Florida on Saturday (March 2).
The "Laguna Beach" star arrived in a sunny yellow sleeveless dress before changing into a gorgeous short red sleeveless party dress with wedge heels to rock the runway.
Beginning at 8:00pm ET on March 1st, 1,440 different cotton looks from the hottest retailers, brands, and designers traveled down the runway.
While prepping for her gig, the 27-year-old former reality star tweeted, "Trying to decide between a retro red or a hot pink lip for tonight's 24 hour Cotton fashion show... decisions, decisions."
