A Note From Our Founder

I created Éssia because I was tired of activewear that made me feel self-conscious. The tight waistbands. The see-through fabric. The constant adjusting.

Our pieces are designed to feel like a soft embrace — comfortable enough to wear all day, elegant enough to feel put-together. No pressure. No perfection required. Just you, feeling good.

— Mayrim, Founder of Éssia Club
