Mark launches nail polish inspired by Kate and William's baby

The British public eagerly awaits the birth of Kate Middleton's son, the Duchess of Cambridge, and Prince William, making every appearance of the couple (and Kate's belly) closely followed.

As is usual in the UK, many brands of various types of products take advantage of current events to launch collections, especially when it comes to the royal family. And in the beauty industry is no different. One example is Butter London nail polish brand, which has just launched a nail polish inspired by Kate's baby.

The shimmering purple-purple product was named after Pitter Patter, referring to the British expression commonly heard by women who are newly married or pregnant: "Will we hear the pitter-patter of little feet soon?", which means something like "Are we going to hear footsteps soon?". The product is already on sale in Butter London's UK stores and e-commerce for £ 15.
