The Formal Collection

That’s exactly where we come in. At T.M.Lewin, we believe formalwear should be stylish, simple, and long-lasting. Whether you’re dressing for a black tie wedding, a charity ball or a special event, a well-cut tuxedo or dinner jacket is a timeless investment — one that, with the right care, can last you 20 years or more.

We’re proud to be a one-stop shop for Formalwear. From the tuxedos and dinner jackets, to the black trousers, shirts, braces, and bow ties, we’ve got everything covered — except the shoes.

Our Formal Collection is made from high-quality fabrics, precision stitching and structured tailoring for a fit that not only looks sharp, but feels incredible too. Because there’s nothing quite like the confidence that comes from wearing a suit that fits just right.

In this guide, we’ll walk through what you need for a full black tie outfit, explain the difference (or lack thereof) between tuxedos and dinner jackets, explore alternatives, and show you how to finish the look from the cumberbund down. And if you're planning a wedding, don’t forget to check out our wedding dress code guide for even more tailored advice.

The Full Black Tie Collection

So, what exactly makes up a traditional black tie outfit?

The classic combination is timeless: a dinner jacket (also called a tuxedo), matching black trousers with a satin stripe down the leg, a crisp white dress shirt, a bow tie, and patent leather shoes. Add-ons like a cumberbund or waistcoat and a pair of cufflinks take things up a notch. Braces (or “bracers”) can be worn too — especially when skipping a belt, which is usually the more traditional option.

When it comes to fit, a slim tuxedo offers a modern edge and flatters most body types, but don’t overlook a classic cut if you prefer more room to move. As for fabric, go for a heavier dinner jacket and quality cotton shirt — you’ll thank yourself on the night.

Every piece in our Black Tie Collection has been made with this kind of occasion in mind: elegant, comfortable, and confidence-boosting — right down to the final stitch.

Tuxedo vs Dinner Jacket

Let’s clear this up once and for all: a tuxedo and a dinner jacket are exactly the same thing.

“Tuxedo” is the term more commonly used in the US, while “dinner jacket” is the classic British name. Both refer to a formal jacket usually worn with satin-trimmed trousers and a bow tie. Whether you call it one or the other, you're still dressing for black tie — and you’ll look sharp either way.

Black-Tie Alternatives

A tuxedo is the gold standard for black tie, but sometimes alternatives are necessary — just tread carefully.

If you don’t own a tux, a sharp black suit can sometimes pass, but it’s always less formal and may not be well received at stricter events. In those cases, it’s best to invest in the real thing.

Want something with a little more personality? A smoking jacket or tailcoat can be appropriate depending on the occasion, but again, only when the dress code allows. They can turn heads — but may also raise a few eyebrows if the host is expecting a traditional look.

If you want to bring in colour, stick to your waistcoat or cumberbund — subtle patterns or tartan fabrics can add flair without going overboard. A crisp white pique waistcoat is another option, which can elevate your look while making it even more formal. Pocket squares, meanwhile, are great for personality — just don’t let them clash.

Below the Cumberbund

When dressing for black tie, the trousers matter just as much as the jacket.

True black trousers for formalwear typically feature a satin stripe and are designed to match the jacket. They don’t have belt loops — which is why bracers or a well-fitted cumberbund are essential to complete the look.

If you must wear a belt, keep it sleek and formal — like our black belt. But really, braces are the way to go.

Shoes? Stick to black leather — patent oxfords or well-polished loafers are ideal. Keep broguing minimal for a cleaner, dressier finish.
