Learn how to make a DIY Professor Trelawney inspired costume with a green dress, accessories, and a upcycled sweater vest.

My husband picked a Harry Potter character costume this year, so I wanted to pick character that would go with it. He picked Professor Quirrell since he’s bald, and I chose Professor Trelawney since I have wavy hair.

I didn’t comb and frizz out my hair for these pictures since it was wash day (iykyk), but I plan on doing that when it’s really Halloween. My wavy hair still worked for these pictures, it’s just not quite as accurate.

The best part of this costume is that I could use a green dress and brown boots that I already had. I thrifted a large, cozy cardigan and turned it into a vest.

I thrifted the head scarf and bought the glasses, and I just used my floral tote bag that I made using my free tote bag sewing pattern. Then my kids let me use one of their toy wands to finish the outfit.

I love being able to use what I have to make a costume, and then buy or thrift a couple of the pieces. All of these things will get used again and again.

I am worried about being cold on Halloween since we have had really cold evenings in the past so I might have to wear a wool coat over top.

Why Make DIY Costumes?

I love to make DIY costumes for my kids for lots of different reasons. I love that I can make something unique that they want and that they’ll love. We live in a cold area so I always have to plan costumes to be warm so that they don’t have to wear a jacket or coat over it.

I almost always save money by reusing fabric and clothing from my stash and around our home, and I have found that reusing clothing saves me time.

Homemade DIY costumes use stronger and more durable fabric that will last through months and years of dress up and play time. I love that the costumes will last longer than one night of trick-or-treating.

Cut the sleeves off of the cardigan at the sleeve/shoulder seam.

Fold the raw edges of the armhole over 1/2 inch. Zigzag around the armhole to keep the edges in place and to finish the edges.
