Hilary Duff knows just how to relax while pregnant -- lots of pampering!

She was beaming as she got a mani-pedi with big sis Haylie Duff in Toluca Lake.

The mama-to-be wore a tight black tank and giant floral bell-bottoms while Haylie wore a silver-and-white striped sweater and long black skirt to the nail salon.

But Hilary must've been influenced by her sister because later that day the two were spotted shopping with Hil's hubby Mike Comrie and Haylie's BF Nick Zano at Confederacy on Hollywood Boulevard, and the 23-year-old actress/singer had changed into an oversized white sweater, black leggings and boots.

If we had a wardrobe as awesome as Hilary's, we'd change twice in one day too!
