Sienna Jean – Black, Stretchy, and Effortlessly Flattering Introducing your new go-to jeans for spring and summer: the Sienna Jean in Black. Crafted from super-stretchy denim, they offer a fitted, high-rise silhouette that flatters from every angle. While they feature a statement button detail at the front, the real closure is a discreet zip fly — giving you the best of stylish design and everyday practicality.

Black, high-rise, super-stretch jeans featuring decorative front buttons and a zip fly for easy, flattering style – perfect for everyday chic.

• Fit: High-rise with a fitted, streamlined shape and subtle flare.
• Design: Decorative front buttons with a practical hidden zip fly.
• Fabric Composition: Ultra-stretchy black denim – soft, sculpting, and comfortable.
• Details: Button-front look without the faff, and a flattering cut that moves with you.

• Machine wash inside out at 30°C.
• Do not tumble dry; air dry flat to maintain the shape and elasticity.
• Cool iron if needed.
• Wash with similar light colours to keep the pale tone bright.

How to Measure Yourself Correctly

Achieve the perfect fit by following these simple measurement steps:

Chest/Bust: Measure around the fullest part of your chest, keeping the tape measure horizontal.
Waist: Measure around the narrowest part of your waist, just above your navel.
Hips: Measure around the fullest part of your hips and bottom, with your feed together.

Ensure the tape measure is snug, but not tight, and parallel to the floor.

*If you fall between sizes, we recommend sizing up for comfort and layering or down if you prefer a snug fit.

• Hil (5'3", UK size 10/12) wears the size M. She wears them with a small heel, which perfectly complements the fit and helps elongate her frame.
• Sue (5'0", UK size 6) wears the size XS. Thanks to the super stretch, she enjoys a close, flattering fit without any tightness at the waist or hips.
• General Rule: As with all our super-stretch denim, stick to your regular size for a fitted shape or size up if you prefer a more relaxed, skimming fit.

We love the Sienna Jean for its gorgeous black and secretly practical zip fly hidden behind those pretty buttons! The high rise and stretchy denim mean they sculpt and move with your body, making them ideal for everything from long lunches to city breaks — stylish and secretly ultra-comfy.

Hil’s Look – Soft & Sophisticated:
Hil styles her Sienna Jeans with a soft ivory blouse tucked in neatly, a slim leather belt, and low block heels. She finishes the look with a pair of oversized sunglasses and a swipe of rose lipstick — perfect for sunny days out.
Sue’s Look – Casual Cool:
Sue pairs her Sienna Jeans with a loose white tee, a lightweight cropped jacket, and chunky trainers. She loves layering up with long necklaces to keep the vibe effortless and a little boho.
