If I've said it once, I've said it a thousand times – slacks and dress pants are two VERY different garments.

They have entirely different fits, styles, and functions.

I know a lot of guys just they're interchangeable – they're both trousers, right? They've both got pockets, belt loops, and legs.

Sure – but a Ferrari and a Ford Fiesta both have 4 wheels, a trunk, and a steering wheel. Are you telling me they're the same thing too?

You want to be the Ferrari, not the Fiesta – so you need to know the basic rules of fit, fabric, and function when it comes to your pants! This is men's style 101, gents.

As ever, it’s my mission to help you look like the best-dressed man in the room, which is why I’m setting the record straight once and for all.

#1. The Differences Between Slacks and Dress Pants

The most significant differences between slacks and dress pants are in their fit, fabric, and function. 

Like any other trouser style, both slacks and dress pants have distinct features. I‘d go as far as to say that they contrast in many different ways. 

Slacks Vs. Dress Pants: Differences In Fit 

What does ‘slack’ mean? Loose, right?

Coincidence? I think not. 

Slacks are loose-fitting trousers designed to fall baggier on the leg. 

Dress pants, on the other hand, can be tighter. Often, they feature a slim design that hugs the thigh to match the tailored silhouette of a formal suit. 

Slacks Vs. Dress Pants: Differences In Fabric

The contrasting construction of slacks vs. dress pants is a result of fabric. 

Slacks are usually made of heavier materials like wool or corduroy. This makes them an excellent option for colder weather or when comfort is a high priority. 

Their heavier construction makes the looser fit essential. A tight-fitting garment made from wool or corduroy would become a sweat disaster! Your skin would have no room to breathe. 

Dress pants are lighter in construction and material. In general, this style of trouser is made from either:

1. Cotton





2. Linen 





3. Polyester





4. A Polyester-cotton mix 

This lighter construction means that dress pants can be slimmer in fit. The thinner/more breathable materials are less likely to cause excessive sweat.

As with any garment in a man’s wardrobe – slacks and dress pants have unique functions. 

Slacks are more informal in their cut and fabric. Wear them in casual/smart-casual environments where a slim silhouette isn’t required. Outdoor fun, family meals, and gatherings are great examples of slack-appropriate events. 

Dress pants, on the other hand, are more formal. As the name suggests, they suit ‘dressier’ situations where formality is the priority. Wear dress pants at the office, to weddings, or on a trip to an upscale restaurant. 

#2. Top Styling Tips For Slacks and Dress Pants

Dress pants and slacks can be styled very differently. As a result of their differing cuts, fabrics, and formality, a man can wear them in very contrasting ways. 

When deciding what to wear with these different styles of pants, you must consider WHY you are wearing them. What occasion are you attending? Are you opting for comfort or a sharp silhouette?

When wearing slacks, a man can sport a more casual style. The looser fit of slacks is similar to that of straight-cut jeans – not too baggy but not too tight. 

The critical thing to remember is not to wear anything skinny/oversized on your top half. This will either make your legs and rear look huge in comparison or make you appear fatter than you are. 

Instead, pair your slacks with regular fit clothing. For example:

1. Light-brown corduroy slacks with a brown belt





2. A light blue Oxford shirt





3. A brown leather strap timepiece





4. Brogue Oxford or Derby shoes in brown 





5. A navy wool sports coat

Dress pants are more formal than slacks, so a slimmer silhouette is often required w
