From his ever-changing hair to his hip attire, we’re always in awe of Kingston Rossdale‘s trendsetting style.

But even we had do a double take when we spotted him in a pink tutu at a friend’s birthday party in Sherman Oaks, Calif. on June 2.

The tyke, who turned 7 on May 26, attended the princess-themed bash with mom Gwen Stefani, dad Gavin Rossdale and little brother Zuma, 4½.

And although Kingston arrived in a cool tee and cargo shorts, he had no problems throwing on the tulle skirt while enjoying the festivities.

He even gave us a peek at his missing front teeth.

Well, hello!

Since her birth last July, we’ve only seen glimpses of Sienna Miller‘s daughter Marlowe.

But on May 22, we were treated to a full look at her adorable face.

The 11-month-old (look at that sweet ponytail!) and her actress mom stepped out in N.Y.C. to grab some refreshments for a sunny walk.

And the always-stylish Miller wore a Rachel Pally tribal-print romper ($220) with her red-and-black Delvaux Madame PM shoulder bag ($3,500) and Lookmatic’s “Marlowe” sunglasses in black tortoise ($130).

Could her chic sunnies be a tribute to her little girl? We think so.

If there’s anyone who could pull off a sartorial nod to their child, it’s definitely Miller.
