We already know Prince George is a fashion icon, but his bathrobe may be starting a new trend.

The 2-year-old son of the duke and duchess of Cambridge was allowed to stay up past his bedtime to meet President Barack Obama and the first lady at Kensington Palace on Friday. Just like most toddlers up late, Prince George was already in his pajamas and blue slippers -- but his bathrobe is what stole the show.

In fact, the little prince's monogrammed, blue gingham trimmed white bathrobe sold out minutes after the picture of Prince George and President Obama went public.

According to CNN Money, My 1st Years, the company behind the 27 pound (about $39) bathrobe is only accepting pre-orders following the international interest.

"We can't believe Prince George wore our robe to meet President Obama," My 1st Years said on Instagram. "Doesn't he look adorable!?"

This is a dream come true for Daniel Price, co-founder of the U.K.-based My 1st Years. He told The Telegraph "its personalized products are meant to be affordable to that everyone can dress their little one like a Prince or Princess."

According to People, Princess Charlotte has the same bathrobe but with a pink gingham trim instead of blue.
