Katy Perry stepped out for dinner in London a few days ago wearing an Acne Mape Leather Jacket ($624.00), an Ashish Enjoy Coke Motif Sequin Top (sold out), boots similar to the Dune Stretchy Leather Round Toe Stiletto High Boots ($251.62) and a skirt similar to the Forever 21 Cool Girl Plaid Skirt ($19.80). You can get a similar jacket from Nasty Gal ($44.00).
