In this DIY, I’m going to show you how to take this very 1980s, very Clueless, very Harry-Styles tweed blazer and turn it into a killer two-piece set. If you're looking for a Cher Clueless Halloween costume, this tutorial is perfect for you.

The original jacket was not actually long enough to become its own cropped jacket and mini-skirt, as it was a regular-length blazer. In most of the tutorials that I’ve seen, the blazer is long enough that really all you need to do is cut it and clean finish it.

However, I have a secret trick that allows you to turn any length blazer into a two-piece set! You can shop your own closet or hit up your local thrift store. Let's get started!

Tools and materials:

  • Tweed blazer
  • Scissors
  • 4-inch wide elastic
  • Ribbing
  • Pins
  • Sewing machine
Cutting the blazer in half

1. Cut the blazer in half

Determine where the middle of the blazer is and cut it in half. The best part about using a plaid or a tweed is that there are straight lines you can follow, and you don’t need to measure or pin anything. Just follow one of the lines, and you’ll have a perfect cut.

2. Add the ribbing

Now you will have your skirt and your top. Obviously, on their own, the proportions are way too small and aren’t going to work. That is where the 4-inch (10cm) wide elastic comes in.

You’re going to sew the elastic to the top of the skirt, which will not only give it a clean finish but also give you four more inches!

Same idea for the blazer; you’re going to add some wide ribbing. The elastic will go on the skirt, and the ribbing will be folded in half and go on the blazer. These additions will give you proportions that will make the finished product feel right.

When you look at the ribbing, you’re going to see a little bit of a clean finish edge that looks a little better on one side than the other. Make sure that that is your front and pin it on the very bottom of your jacket.

Pin the ribbing all along the bottom of the jacket. Do it across the front first, picking one line on your tweed to line it up so that it’s going straight all the way around the back.

Then, you’re going to fold the other side over, fold it right in half and pin it so that it’s like sandwiching the bottom of the jacket. It almost acts as a bias tape.

For the ends, take the end and fold it all the way over on the top and bottom. When you do the sandwich effect and fold it in half, it will be clean-finished everywhere.

To sew, leave a very small seam allowance, maybe ⅛ inch right along the edge of the black ribbing, and sew it into place.

3. Add the elastic

For the elastic, start by measuring how much you need for your waist and sew it together. Place it on top of the skirt with the right sides touching, so you’re looking at the wrong side of the elastic. You’re going to sew it and flip it.

Pin the elastic to the skirt, start with the center front, center back, right side, left side, and then evenly distribute any excess throughout the skirt. Pin it all the way around, and then put it on to see if you’re actually able to get the skirt on without needing to add in a zipper.

When happy with the measurements, sew the elastic with a simple straight stitch, stretching your elastic a little bit as you go with a ¼-inch seam allowance. Sew it all the way around and then just fold up the waistband.

4. Topstitch the skirt

I wanted to sew down the open part at the front of the skirt, but I decided to topstitch everything as a design detail. I topstitched the seam where the elastic was on the top, and then I just followed it and hemmed the entire piece with this little detail.

    It’s not the same. At all. The trend of short cropped everything is hopefully fading out. The 90s were also quite baggy. Most clothing has a good bit of fabric folded under and hemmed. Just let the seam out least use it to add length if you need it.
