Hilary Duff  sunglasses luca rag and bone boots

He's the most stylish baby around!

Hilary Duff stepped out in a stylish outfit to take son Luca to a playdate yesterday, and she made sure her little man was on point with his style as well! The adorable little boy was dressed in plaid shorts and moccasins, and it looks like he's channeling fellow fashionable celeb tot Mason Disick!

Just the other day, Hil and Luca enjoyed a playdate with Jack Osbourne's wife Lisa Stelly and daughter Pearl, so it seems the Lizzie Maguire star is making sure her son's schedule is jam packed with socializing opportunities!

Life isn't constant mommy duty, though!

Her husband Mike Comrie must have been on baby watch, because the blonde beauty managed to squeeze in a relaxing sauna session with her sister Haylie yesterday.

The ladies even tweeted a pic of themselves looking sweaty with no makeup! That takes nerve!
