4B W5359 Blazer Nappa Leather Skinny Tulle Stretch Back - Black Women's Jacket

Leather That Moves Like a Second Skin

The 4B W5359 is a study in contradiction: a skinny blazer cut from 100% nappa leather, lined in stretch fabric, with oversized sleeves and a stretch tulle insert across the back. It is structured where it needs to be and fluid where it doesn't. LA HAINE INSIDE US engineers this tension deliberately — the result is a leather jacket that fits like a blazer, moves like a knit, and looks like nothing else.

Why This Blazer Is Different

• 100% Nappa Leather Shell: Full-grain nappa is the softest, most supple leather available — it drapes rather than stiffens, conforming to the body with wear.
• Stretch Tulle Back Insert: A panel of 90% polyester / 10% elastane tulle replaces the traditional leather back, allowing full freedom of movement and creating a graphic contrast between opacity and transparency.
• Stretch Lining: The interior lining moves with you — no pulling, no restriction, no compromise on fit.
• Porthole Shoulder Details: Circular cutouts at the shoulders are a LA HAINE signature — architectural punctuation on a precision-cut silhouette.
• Oversized Sleeves: Volume at the sleeve against a skinny body — a deliberate proportion play that reads as sculptural, not accidental.
• Double-Slider Zip Closure: Open from top or bottom for precise fit adjustment and styling versatility.
• Zip at Sleeve Hem: Functional zip at the bottom of each sleeve for a clean finish and adjustable cuff.
• Made in Italy: Designed and produced in Italy — every seam, every zip, every porthole placed with intention.

The Moment You Put It On

Nappa leather has a temperature — cool at first, then it warms to you. The skinny cut sits close to the body, the stretch lining moving with every breath. Then you notice the back: the tulle panel catches the light differently, translucent against the opacity of the leather, a window cut into the structure.

The portholes at the shoulders are small but precise. The double-slider zip gives you control over how much of the front you reveal. This is a jacket built for people who understand that the details are the design.

The Art of Nappa Leather

Nappa is a full-grain leather known for its exceptional softness and fine grain. Unlike corrected-grain leathers that are sanded and coated, nappa retains the natural surface of the hide — which means it breathes, it develops a patina, and it becomes more beautiful with age and wear. LA HAINE INSIDE US selects nappa specifically for its drape: in a skinny blazer cut, it needs to move with the body rather than against it. The result is leather outerwear that feels closer to a second skin than a structured shell.

How to Wear It

• Total Black: Over a black bodysuit and slim trousers — the porthole details and tulle back read as texture within a monochrome register.
• Sharp Contrast: Over a white shirt with tailored trousers and pointed-toe heels — the leather blazer as the power layer.
• Dressed Down: Over a fitted turtleneck with straight-cut jeans and ankle boots — elevated without effort.
• Evening: Over a slip dress or satin top — the skinny leather silhouette adds edge to anything fluid beneath it.

Care Instructions

• Do not wash — professional leather cleaning only
• Store on a padded hanger away from direct sunlight
• Condition with a leather-specific product seasonally
• Allow to air dry naturally if wet — never use heat
• Avoid prolonged contact with light-coloured fabrics to prevent colour transfer

Leather is not a material — it is a commitment. It asks for care and returns character. LA HAINE INSIDE US. 100% Nappa Leather. Made in Italy.
