Selma Blair and son Arthur make a perfectly pink pair in matching shirts as they take a trolley ride

At 21 months old, chances are slim that Selma Blair's little boy is choosing his own clothes.
And mum seems to be just fine with that.
The 40-year-old actress dressed herself and her son Arthur in parallel pink outfits for a day at The Grove in West Hollywood on Thursday.

Perfect in pink: Selma Blair and her 21-month-old son Arthur awaited a trolley ride at The Grove in West Hollywood on Thursday wearing matching outfits

The mother-son duo headed to the outdoor shopping mall for some quality one-on-one time.
Skirting the shops, however, the Cruel Intentions actress had another main attraction in mind for her baby boy.
Standing patiently by the rail, the two waited to board the trolley, which runs the length of the retail centre.

The picture of spring: In pastel pink tops and light chino shorts, the two deflected the bright Southern California sunshine

Impossible to miss, both Selma and Arthur sported light pink tops.
The actress opted for a linen striped button-down blouse that she tucked into mid-length white chino shorts.
Though she usually has a taste for the unusual when it comes to fashion, she kept it simple with just a pair of aviator sunglasses and a white handbag to accessorise.

Ready to ride: Selma's rambunctious little boy got a little too excited while waiting for the trolley ride and was tempted to climb the railing

Hats off: Little Arthur practised his style prowess with a straw fedora

Arthur's summery accoutrements, instead, stole the style spotlight.
A pink T-shirt with a popped-collar topped chartreuce shorts and brown leather sandals.
His straw fedora hat added just the right amount of prep.

Two for the trolley: The duo enjoyed their time riding throughout The Grove, especially curious Arthur

The toddler couldn't keep his eyes off the trolley and looked glum when it came time to exit the ride.
Arthur is Selma's child from a relationship with designer Jason Blieck, with whom she split in September.
Selma currently stars in hit series Anger Management - now in its second season - alongside Charlie Sheen.
