Is this a real tuxedo jacket?

No. It is a single-breasted velvet jacket in a slim cut, described as smart casual. It reads as a dinner jacket for parties and weddings, not for strict black tie, which calls for satin-faced lapels and matching trousers.

What is the fabric like?

It is a blend of acetate, cashmere, cotton and polyester. That gives a soft velvet pile with a little body, softer than all-polyester velvet but less structured than wool.

How does the slim fit run?

Slim fit sits close to the body through the chest and shoulders. If you are between sizes or broad-shouldered, consider sizing up so it layers over a shirt.

Can I wear it outside formal events?

Yes. The casual styling works over a plain shirt or fine knit with dark trousers for dinners and parties. Keep the rest of the outfit simple so the velvet stays the focus.
