Vest Union Suit - Black

Introducing our softest union suit yet ☀️

Meet the Summer 2026 Cotton/Lyocell Vest Union Suit — designed for summer days, warm nights, and effortless comfort.

Crafted from a luxurious cotton–lyocell blend, this new lightweight fabric feels silky-soft to the touch,  fits perfectly on the body, and keeps you cool, breathable, and comfortable all day and night long. It’s the perfect balance of cotton’s familiar comfort and lyocell’s next-level softness and performance.

Designed with a tonal chest logo embroidery, racer back styling and full popper fastening from the neckline all the way down, around, and to the bum — it's the DEN Union Suit styling you know and love, remixed for the new season! 

Naturally breathable, moisture-wicking, gentle on sensitive skin, and more wrinkle-resistant than pure cotton, this is our most comfortable summer union suit to date — made to move, lounge, sleep, and live in.

Once you put it on, you won’t want to take it off.
