DIY Princess Peach Super Mario Costume (VIDEO Tutorial)

I’ve been wanting to do a DIY Princess Peach Costume for Halloween for awhile. I prefer to do more classic or nostalgic costumes instead of the year’s ‘IT’ costume.

Outfit

I am not a gifted sempstress but I somehow pieced this outfit together without a pattern; I will never do that again! There are definitely some flaws with the outfit – the pleats aren’t completely even and some seems are worse for wear. However the costume did last the night.

Princess Peach Costume Pieces

What I DIY’d

• Top
• Skirt
• Crown
• Cameo
• Earrings

Bought

• Gloves
• Kness Highs

Skirt Supplies & Instructions

• Two colours of pink satin fabric (mine is a polyester blend without much stretch). The bit of fuchsia fabric is for the waistband and collar.
• Matching thread
• Two zippers (one for the skirt one for the shirt)
• Elastic to make the sleeves puffy

For the skirt measure your waist and allow for some seem allowance (approximately an inch to an inch and a half extra). Cut out a rectangle per your waist measurements and your desired width. The strip will be folded in half for the waistband. Make the skirt fabric at least double this.

Put interfacing in between the waistband fabric and fold in half while securing with the iron. I use fusible interfacing. If you don’t know what interfacing is it basically makes fabric sturdier. I then started pinning the light pink skirt fabric to the waistband and making pleats. As noted I didn’t realize this fabric would show mistakes so obviously, I wish I would have actually measured instead of eyeballing the pleat intervals. I used the same technique on my Effie Trinket costume and you couldn’t tell. You’ll end up with a piece that looks something like the below picture (but I didn’t line my pink skirt). Sew the side seem and add a zipper.

Puffy Sleeve Shirt

For DIY Princess Peach Costume top I traced a form fitting shirt I owned already, knowing I’d be adding a zipper to the back to get into the shirt. I used the same interfacing technique for the collar.

If you can see the sleeve outline below notice the straight edge is for the elastic and the dome is to be attached to the armpit. Measure your arm and make the elastic slightly smaller. Fold the straight edge and sew. Feed the elastic through the pocket. Pin the dome to the armpit like you did with the skirt – at varying intervals. Sew to armpit and sew elastic closed. You will then have pouffe sleeves.

Princess Peach Accessories

Princess Peach Crown

Supplies

• Gold wire (thin and thicker)
• Gold beads and crystals
• Blue crystals
• Red crystals

I’m a jewelry maker as my side hustle (see my Etsy!) so I have tons of bead and jewelry supplies already. I wanted to use up what I had and be a bit different. Also learning a new technique to make a plastic crown was too time-consuming. I really just made this crown up as I went around; but here is an overview of the process.

1. Take two pieces of the thicker wire and twist them to each other. One will make your base the other the points for the crown.
2. String beads in pattern on base – this will be how wide the triangle is.
3. With non-base wire string beads and twist top bead in a point when you get the desired height. String same pattern on other side so either side of the points match.
4. Repeat pattern on base and points four times so they match.
5. Twist a thin wire in the triangles and make a pattern of gold and the blue and red beads.
6. Attach to a headband or a comb.

Accessories

Cameo Supplies

• Plastic dome
• Cameo base
• Mod Podge
• Gold and blue sparkles

Instructions

1. Paint Mod Podge on cameo base, don’t cover entire middle.
2. Sprinkle gold sparkles and let dry.
3. Paint middle of cabachon with Mod Podge and sprinkle blue sparkles.
4. Once dry glue clear dome in centre.

For the earrings I used blue crystals, gold wire and found a tutorial for a beaded sphere. I added a bead on top and attached it to an earhook.
