La Roux Costume

Find a plain white blazer or jacket to start. Try thrift stores or Etsy vintage.

Remove pockets (if it has any) from the jacket with a seam ripper.

Create a pattern from one of the pockets by tracing it onto paper.

Use a ruler to "square off" the corners.

Cut pockets from a thick folded layer of each colored fabric.

Make sure the fold is at the top edge of the pocket.

The yellow and green pockets are rectangular, so I squared up my pattern before cutting the square red and blue ones.

Cut and iron a ton of 3/4" wide black binding. If I had to do it over, I'd probably order some black bias tape.

Pin binding around 3 raw sides of pockets, leaving the layered fold at the top.

Straighten the front flaps of the jacket by opening up the seam with a seam ripper.

Cut off the excess fabric and use an iron to press in a new, straighter flap. Sew with white thread.

Pin and sew binding to jacket around the front edges, inside of collar, and cuffs.

Because the bottom front corners of my jacket weren't square, I fudged it by extending the binding out past the edge.

Pin and sew on pockets!

There's a bit of binding detailing over the shoulders and on the sides as well.

Sew on five black buttons. Don't worry about buttonholes, you'll wear the jacket open!
