Tools and materials:

  • Black corset top
  • Thin crystal trim
  • Thick crystal trim
  • Wire cutters
  • Glue
  • Syringe
  • Brush
  • Black paint
  • Mesh top with rhinestones (optional)
Prepping glue for the spider web costume DIY

1. Prep the glue

The first thing you’re going to do is fill up a precision syringe with your glue of choice. Fill about half of the syringe, as you’ll need less than you think.

2. Glue the thick crystal trim

Now, line the upper seam of your corset with glue.

Push the thick crystal trim down on the glue. The precision syringe is vital since it will spread evenly and not seep through the sides when you push down on the trim. 

Gluing along the upper seam

Continue doing this on the entire upper seam, as shown. 

Carefully place the trim on the curved edges

When you get to the curved edges of the corset, a thick trim is not flexible enough to bend around the edges, so doing it in two pieces is the trick.

3. Make the spider web

Now, it’s time to make the spider web design on the bust cups. You can eyeball it by drawing the design with a pencil. Then, glue down the pieces accordingly. Start by creating an even “X” shape.

For every piece you glue around the bottom half of the cup, cut the trim further down, so you have a lovely fringe effect. Also, you cannot overlap the crystal trim, so to form the other line for the “X” part, you’d have to cut the piece in half and stick accordingly, all around.

Next, anchor a long piece of crystal trim in between the triangles to create that cobweb effect. Here, you can overlap the trim on top of the diagonal pieces.

Here’s a closeup. Round each segment as you go along, and then glue the trim on top of the glue accordingly. 

Creating a spiderweb pattern on the corset

Let the crystal trim fall on the trim underneath so that you achieve a dangle effect. Work your way around the cup so that you have at least three sets of these.

Essentially, you need to anchor the points appropriately, and the finished result looks like this.

Touching up with black fabric paint

If there are overspills of glue, scrape off the glue with your fingernails and touch it up with some black fabric paint. Finish off the spider web costume by adding trim to the bottom edge. 

Mesh top with rhinestones to go underneath the corset

4. Mesh top (optional)

I purchased this mesh top from a store, and it has some lovely rhinestones all over the fabric. I plan on wearing this underneath the corset top.
