Jessica Simpson looks warm and cozy in her matching suede boots and gloves, fuzzy coat and furry ear muffs while working the crowd at the 84th Annual Macy's Thanksgiving Day Parade in New York.

While rolling along the streets of NYC on top of a decorative float, Ms. Simpson braves the chill ... and even looks overcome with emotion as a sea of fans cheer from below!

Oh, Jessica ... falling in love has certainly done you wonders. Look at that glow! Fiance Eric Johnson is one lucky guy.
