Slacks is one of those menswear terms that gets used loosely, which leaves many men unsure what it actually means. Slacks for men are smart, tailored trousers, cut from finer fabric and traditionally worn as separates rather than as part of a suit. They sit toward the dressier end of the trouser scale, offering a polished look without being as formal as suit trousers. Here is a clear guide to what slacks are and when to wear them. When you are ready, you can shop formal trousers at Italian Colony.
The Simple Definition
The term slacks describes tailored trousers designed to be worn on their own rather than with a matching jacket. They are typically cut from smooth, finer fabric with a clean line, which gives them a smart, considered look. In everyday use, mens slacks sit at the smart-to-formal end of the scale, dressier than chinos but often a touch more relaxed than strict suit trousers.
Slacks vs Other Trousers
| Type | Formality | Best For |
|---|---|---|
| Suit trousers | Most formal | Suits, formal events |
| Dress slacks | Smart to formal | Office, smart occasions |
| Chinos | Smart-casual | Versatile everyday |
| Relaxed trousers | Smart-casual | Everyday comfort |
Slacks bridge the gap between strict suit trousers and casual chinos, which is what makes formal slacks so useful for the office and smart occasions. Explore smart options in the Formal Trouser collection.
When to Wear Slacks
Slacks are ideal for smart and professional settings where a full suit is not required. They are a natural fit for the office, smart dinners, and events with a smart-casual or business-casual dress code. Worn with a shirt and leather shoes, dress slacks look polished and put-together, and they can be dressed down slightly with a fine knit for a softer smart look.
The Best Colours for Slacks
Neutral colours make slacks most versatile. Charcoal and grey are the most professional and pair with almost anything, black is sharp and easy, and navy adds a smart classic option. Starting with charcoal or grey gives you a pair that works across the widest range of smart settings.
Slacks or Relaxed Trousers?
If you need a smart, polished look for professional or formal settings, slacks are the right call. For everyday comfort and smart-casual wear, a relaxed trouser is more versatile and easy, so explore the Relaxed Trouser collection. Many men own both, using slacks for smart occasions and relaxed trousers for daily wear.
