Hilary Duff

Hilary Duff had little Luca Comrie on her hip to run errands in LA yesterday. Afternoon outings are regular occurrences for Hilary and her son. Last week, Hilary took Luca to a Babies First Class session before a shopping trip together. Between the many outings, Hilary has also been focused on getting back into shape after giving birth to Luca back in March. It appears that all of her hard work at the gym has paid off. Hilary shared a snap of her size 26 skinny jeans and thanked her trainer, Gabe Johns, for his help just a few days ago.

Hilary Duff brought little Luca Comrie to a Babies First Class session in Sherman Oaks, CA, before the duo went shopping in Studio City yesterday. Hilary toted her plaid-clad baby boy around after attending the class for new parents and babies. The pair then visited a children's store, where Hilary picked out new duds for her growing 8-month-old. Hilary already showed off some of Luca's Winter gear when she tweeted a picture of her "main men" on a recent trip to Canada. Hilary's husband, Mike Comrie, took Luca sledding while celebrating Thanksgiving with their family.

Hilary Duff had her almost 8-month-old son, Luca, on her hip as she headed into a grocery store in LA yesterday. Luca was bundled up in a hat while Hilary wore a scarf and floral Level 99 jeans to protect against the chilly West Coast weather. Luca just celebrated his first Halloween. The little guy also reached another milestone — crawling! Hilary recently talked to Parenting magazine about motherhood, sharing that she stays focused on working out because she's "so grateful to be able to escape for an hour a day and clear my head. I feel like it makes me a better mom."

It's no secret that in Hollywood, trends come and go, but Rag & Bone's Harrow ankle boot has proved a closet staple season after season. Everyone from Reese Witherspoon to Hilary Duff to Nina Dobrev to Emma Stone has nabbed a pair in various colors. We particularly love the way Rachel Bilson paired her tan Rag & Bone booties with cuffed jeans and a colorful scarf in NYC.

Cruise through to see which other celebrities were spotted donning this versatile ankle boot, then shop the Fall essential for yourself.

Hilary Duff was joined by her tiny shopping buddy, Luca Comrie, in LA yesterday. The pair were spotted browsing through a few furniture stores in West Hollywood. While it appears Hilary is shopping for her home, sister Haylie recently listed her Toluca Lake home for $1.8 million. Haylie's been spending time hanging out closer to the beach, and it seems she's following in her sister's footsteps by moving out of the Valley. Earlier this year, Hilary and husband Mike Comrie sold their own Toluca Lake home for a whopping $6.25 million.
