W5416 Blazer - Black Stretch Ecopelle Tulle Back Insert Internal Shoulder Straps Sleeve Vents Buttons Flap Pockets Women's Italian

Stretch Ecopelle. Tulle Back Insert. Sleeve Vents and Buttons. The Faux Leather Blazer With Tailoring Details.

The W5416 is a blazer in stretch ecopelle — 50% polyester, 50% polyurethane — fully lined in 100% polyester, with internal shoulder straps, a stretch tulle back insert (95% polyester, 5% elastane), a button closure, flap pockets, and sleeve vents with buttons. Three construction details that elevate the stretch ecopelle blazer beyond standard faux leather: the stretch content allows the ecopelle to move with the body; the tulle back insert opens the back while maintaining the blazer silhouette; the sleeve vents and buttons are a classic tailoring detail applied to a non-traditional material. Made in Italy by LA HAINE INSIDE US.

Why This Blazer Is Different

• Stretch Ecopelle: 50% polyester, 50% polyurethane — ecopelle (Italian for “eco-leather”) is a polyurethane-coated fabric that replicates the appearance and hand of leather without animal materials. The 50% polyester base provides structure and durability; the 50% polyurethane coating creates the leather-like surface. The stretch content in the base fabric allows the ecopelle to move with the body — unlike standard faux leather (which is rigid and restricts movement), the stretch ecopelle of the W5416 follows the body without cracking or distorting the PU surface.
• Stretch Tulle Back Insert: 95% polyester, 5% elastane — the back panel of the blazer is constructed from stretch tulle rather than ecopelle. Tulle is a fine, open-weave net fabric; the stretch tulle back insert creates a back that allows air and light through while maintaining the blazer silhouette from the front. The contrast between the ecopelle body and the tulle back is maximum: the solid, opaque, leather-like ecopelle at the front; the open, semi-transparent tulle at the back. The stretch content in the tulle ensures the back panel moves with the body.
• Sleeve Vents and Buttons: Vents at the sleeve cuff with buttons — a classic tailoring detail typically found on wool or cotton blazers, applied here to stretch ecopelle. The sleeve vents allow the cuff to be opened or adjusted; the buttons add a precise, tailored finish to the ecopelle sleeve. This is an unusual detail for faux leather — the tailoring precision of the sleeve vents and buttons contrasting with the material of the ecopelle.
• Internal Shoulder Straps: Straps sewn inside the blazer at the shoulder — a construction detail that holds the blazer in place on the shoulder without visible external hardware. The shoulder straps ensure the blazer sits correctly on the shoulder regardless of movement.
• Flap Pockets: Front pockets with flaps that maintain the blazer's structured silhouette.
• Button Closure: A single button closure that keeps the ecopelle front panels in place when closed.
• Made in Italy: Stretch ecopelle construction, tulle back insert finishing, sleeve vent construction, and all finishing completed in Italy under LA HAINE INSIDE US's atelier standards.

Women's Size Chart

Note: Model wears XS. Height 180cm, bust 85cm, shoulders 41cm. Regular fit — true to size. The stretch ecopelle moves with the body; the blazer does not restrict arm movement despite the PU surface.

The Moment You Put It On

The stretch ecopelle is immediately different from standard faux leather — the PU surface smooth and leather-like, but the stretch content allowing the blazer to move with the body without the rigidity of standard faux leather. The internal shoulder straps hold the blazer in place; the button closes the front with a single, clean click. The flap pockets sit flush with the ecopelle body.

Turn around and the stretch tulle back insert is revealed: the open, semi-transparent tulle replacing the ecopelle at the back, the blazer silhouette maintained from the front while the back breathes and allows light through. At the cuff, the sleeve vents and buttons: a tailoring detail in an unexpected material, the precision of the vent and button contrasting with the leather-like quality of the ecopelle sleeve.

The Art of Stretch Ecopelle

Ecopelle (Italian for “eco-leather”) is a polyurethane-coated fabric that replicates the appearance and hand of leather without animal materials. Standard ecopelle is rigid — the PU coating creates a surface that does not stretch, restricting movement and cracking at stress points over time. Stretch ecopelle adds a stretch base fabric (polyester with elastane) beneath the PU coating, allowing the ecopelle to move with the body without cracking or distorting the surface. In the W5416, the stretch ecopelle is 50% polyester, 50% polyurethane — the polyester base providing structure and durability; the polyurethane coating creating the leather-like surface. The stretch content allows the blazer to follow the body at the shoulder, arm, and back without the restriction of standard faux leather.

How to Wear It

• Button Closed, Classic Front: Close the button and wear the blazer as a structured, leather-like piece — the stretch ecopelle body visible at the front, the tulle back insert revealed when you turn.
• Over a Turtleneck: Wear over a fitted black turtleneck and slim trousers — the stretch ecopelle blazer over a minimal base, the tulle back insert and sleeve vents the focal points.
• With Wide-Leg Trousers: Wear with wide-leg trousers — the regular-fit blazer creating a deliberate proportion with the wide-leg below.
• All Black: Combine with other black pieces — the ecopelle surface creates natural variation within an all-black palette, the tulle back insert adding texture and the sleeve vents adding tailoring detail.

Care Instructions

• Wipe clean with a damp cloth — the stretch ecopelle surface is water-resistant and does not require washing
• Do not machine wash or dry clean — the PU coating will be damaged by water immersion or dry cleaning solvents
• Do not tumble dry or iron — heat will damage the PU surface
• Store hung — avoid folding the ecopelle, which can crease the PU surface permanently
• Keep away from direct sunlight for extended periods — UV exposure can degrade the PU coating over time
