Ever since the day Kate Middleton and Prince William announced their engagement in 2010, the world has watched the Duchess continue to wow us with her impeccable fashion sense.

Probably her most well known outfit, the blue wrap dress she wore for the announcement, has a simple elegance to it, matching perfectly with the family ring William gave her.

If you’re still stumped on what to dress up as for Halloween, here is a simple yet sophisticated suggestion: Go as Kate Middleton.

You might even already have a pair of black heels in your shoe closet somewhere. All you’ll need is a blue dress and a ring that looks similar to her engagement ring and you’re good to go!

I’ve done some of the work for you below with some items that look similar to the originals on Kate. For a makeup tutorial to complete the look, check out the YouTube video as well!
