My first Wonder Woman breastplate cracked down the center seam on wear number three. I'd skipped the body cast, eyeballed the curves, and used pure EVA foam with no backing. It looked fine on the table. On my actual torso, bending to sit in a panel chair, the waist flex point split clean open. That was build one. Build two is the one I'm going to walk you through.

The body cast is the entire foundation and you cannot shortcut it. Wrap your torso in saran wrap (wear a tight tank top underneath, you'll thank me), then layer duct tape over it in strips until you have a rigid shell. Have a friend cut you out up the back. That shell becomes your dress form, and every breastplate panel gets drafted on it with a Sharpie. The DCEU breastplate has compound curves that don't exist on any commercial dress form. Your ribs curve differently than mine, your bust point sits higher or lower, and if you skip this step you'll get a plate that gaps at the sternum or digs into your floating ribs after forty minutes on the con floor. I spent an entire Saturday on the cast and pattern drafting. It felt like wasted time. It wasn't. Every piece I shaped after that fit on the first try because the pattern was actually my body.

I use Worbla's Black Art over a 2mm EVA foam base. Black Art because its activation temperature is higher (around 100C versus 80C for Finest Art), and I've worn this at outdoor summer cons in Southern California where pavement temps hit triple digits. Standard Worbla sags in direct sun. Black Art holds. The foam underneath gives flex so it doesn't crack when you sit or twist. Heat your panels and drape them over bust forms shaped from balloons matched to your cup size. Not a flat surface. Not a bowl.

For finishing, prime with three coats of Flexbond, sanding lightly between each. Then a flat black base, then Rub 'n Buff Gold Leaf applied with your fingertip. A pea-sized dab covers more than you'd expect. Buff with a microfiber cloth. Seal everything with Krylon matte clear coat or the gold will transfer to your skin, your wig, and your friend's white shirt when they hug you.

The tasset skirt is straightforward but test it early. Cut your faux leather strips with a slight taper (wider at the bottom) and attach them to a separate belt with Chicago screws so they hang independently from the breastplate. I sewed small washers into the bottom hems to keep them from flipping up on windy days or stairs. I picked up my faux leather at the Joann in Torrance on Hawthorne Blvd, two yards for about $24 on a 50% off coupon day.

Bracers, greaves, tiara, and lasso are secondary builds that go faster once the breastplate is done. Shape your bracers with your arm slightly bent or they'll pinch at the inner wrist. The tiara is a scrap of Worbla with Rub 'n Buff and a silicone wig grip strip glued inside. Mine hasn't moved in three full con days.

Budget lands between $180 and $450 depending on whether you already own a heat gun and how much Worbla you waste on test pieces. I wasted $30 in Worbla on my first breastplate attempt before getting the shaping right. Eight weeks is realistic with evenings per weeknight and longer weekend blocks for priming and painting. The body cast week feels slow. Do it anyway. The rest moves fast when fit isn't something you're fighting.
