Men's Shawl Collar Tuxedo (Dinner Jacket)

Two-Button Tuxedo Jacket with Shawl Collar, Flap Pockets with Welts & Center Back Vent

Introducing a digital men's sewing pattern for the semi-formal jacket with shawl collar – Versatile Elegance with a Modern Edge.

When To Wear

This jacket adapts the sophistication of a tuxedo into a more versatile garment, ideal for:

• Evening Receptions & Parties: a refined option when formal flair is desired without strict black-tie rules.
• Weddings & Celebrations: Suitable for grooms, groomsmen, or guests seeking elegance with flexibility.
• Concerts & Special Events: a polished jacket that pairs equally well with tuxedo trousers or tailored separates.

Key Design Features

Silhouette: Single-breasted tailored jacket with a slightly softer, more versatile line than a traditional tuxedo.

Collar: One-piece shawl collar, cut together with the front, shaped to meet a two-button closure. Satin or silk may still be used for contrast, though optional.

Closure: Two-button front fastening, lowering the formality and offering a more contemporary balance.

Pockets: Welt chest pocket; two lower flap pockets with welts.

Sleeves: Full-length, two-piece tailored sleeves with vents.

Level Of Difficulty

Advanced. Precision tailoring is required for the shawl collar, welt pockets, and structured fit.
