Prince George's overalls sell out online

LONDON (KTRK) -- He's becoming a fashion icon, and he's only 1.

We're used to seeing the clothes that Kate Middleton wears sell out in just hours, but now the same can be said for Prince George.

Just last week, photos were released of Prince George celebrating his birthday early. He was with mom and dad at the Sensational Butterflies exhibit at the Natural History Museum wearing a pair of striped overalls. Now, the overalls are sold out online.

The outfit came from Petit Bateau and cost $45.

If it's Prince George's wardrobe you're after, his shoes are still available online. Hurry, because these may sell out too. The navy Alex Pre-Walkers from Trotters are nearly $48.
