Tonight there will be an opening party for the newest addition on London’s Mount Street, as Lanvin first London boutique opens its doors.

Balenciaga, Marc Jacobs and Christian Louboutin have all opened stores on the same street in the past six months, so it’s in great company.

The new Lanvin store will have five floors of Parisian chic wrapped-up in a Grade 2 listed building, adding to Mount Street’s allure.

If you can’t get yourself to Mount Street, you can purchase Lanvin online.

Browns Fashion, and Matches Fashion have a whole range of Lanvin pieces. Net-A-Porter have accessories and shoes.

If you love Rita Wilson and Tilda Swinton’s stunning Lanvin pearl and chain sequin necklace, you can purchase it from Luisa via Roma for €1,026.

Rita seems to be wearing two, to add more drama to her satin aqua strapless gown.
