Who is Jillea?
Hi! I'm a costume designer and whimsical artist with over 12 years of experience in the industry. I started out as a musician, but my passion for over-the-top fashion, stage performance, and artistic expression led me to naturally pivot into professional cosplay and costume design. I've made a name for myself with bold, inventive designs using unconventional materials—like the iconic Diet Coke can corset I created for Julia Fox, which gained worldwide attention.
My work has been featured in major outlets like Vogue Germany and Teen Vogue. I’ve become a go-to designer for celebrity Halloween costumes, often landing my pieces on the best-dressed lists, especially at Heidi Klum’s famous Halloween party. With a keen eye for detail and a knack for creating both imaginative and wearable pieces while thinking outside the box, I continue to push boundaries and captivate audiences with my creativity and whimsical approach to costume design and cosplay.
I can't wait to teach everything I've learned over these years!
