On Monday the royal family descended upon the Chapel Royal at St. James’s Palace for Prince Louis’s christening.

While the royal baby was dressed in the traditional Honiton lace gown, all eyes were on his older siblings, Prince George and Princess Charlotte, who sported special outfits of their own.

If it’s possible for 3-year-old to have a signature look, then Princess Charlotte’s is certainly pretty blue smock dresses and matching bows.

Wearing a baby blue floral number with puff sleeves, the princess paired her dress with Doña Carmen blue shoes costing €29.95 (about $35 U.S.) and a bow headband by Pepa & Co, which retails for just £7 (or $9 U.S).

Her 4-year-old brother, George, wore navy blue shorts and a white button-front shirt with blue trimming by Amaia Kids.

Both of the outfits are sure to have sell-out potential. Princess Charlotte’s enormous hold on the fashion industry continues, with many of her outfits selling out instantaneously.
