If you want Princess Charlotte's blue dress from the day she met her newborn baby brother, you might want to consider your other options. To not much surprise, the little royal's frock sold out within 24 hours after she so happily and adorably debuted it at the Lindo Wing on Monday, April 23.

The blue floral dress is designed by Little Alice London and goes for £45.00 or about $63. However, the brand has marked on their website that the item is officially sold out. The smock — which is typically available for everyone from ages six months to six years — isn't just sold out in Char's size either, it's sold out in every size.

While we can admit that Charlotte's dress was cute, we can't just forget about her adorable wave to royal fans as she made her way into the hospital with dad Prince William and brother Prince George. Apparently, the two-year-old was thrilled to be there. "George and Charlotte were with the baby for 25 minutes and were very excited to meet their new sibling," an insider previously said to Us Weekly.

A source also recently told Life & Style that Charlotte and George have been excited since they found out their mom was pregnant. "They rub their mum’s tummy and talk to the new baby. George and Charlotte really are both lovely, normal kids," a family friend told the magazine. So cute!

The royal baby's name has not been announced to the public yet, but William gushed about his newborn son on Wednesday, April 25. "Sleeping’s going reasonably well so far, so he’s behaving himself which is good," he shared.

And now, the royal family feels complete with their newest addition. Royal biographer Ingrid Seward told People, "It completes them. [Kate] is one of three siblings, and it’s a good family size. Boy-girl-boy is pretty cool as well."
