But what exactly are slack pants and how do they compare to other suit pants? Read on to find out about the differences and similarities between dress pants, dress slacks, tailored slacks, semi-formal pants, and more!

The development of pants came alongside horses' domestication and served as an indicator of class and profession. Now, slacks are a type of dress pants that are commonly worn in formal or business settings and live in a man's wardrobe.

They are typically made from more formal fabrics such as wool, polyester, or a blend, and often have a straight cut and a crease down the front of each leg.

An Introduction to Slacks

The term "slacks" is often used interchangeably with "dress pants," but slacks tend to have a dressier, more tailored appearance compared to other types of formal pants.

Essentially, slacks are dress pants with a tailored, formal appearance, typically worn for professional or semi-formal occasions.

While slacks were once considered to be a staple in the wardrobes of working men, they have since evolved to become a versatile and stylish option for both men and women.

It's a great idea to pair slacks with dress shirts and a matching jacket or formal suit depending on the dress code. Here's a guide on how to wear grey pants with brown shoes.

Despite their dressy reputation, slacks can also be worn in more casual settings depending on the style and material of the pants and the overall outfit. Khakis slacks or beige slacks, for example, are a popular choice for a casual or business casual outfit and can be paired with a variety of shirt colors like blue dress shirts and patterns like this blue patterned shirt.

The history of slacks and their evolution in men's fashion

Slacks, typically lightweight pants with a relaxed fit, have a long history in men's fashion. Slacks are a type of pants that are typically made from lightweight fabrics and have a more relaxed fit than men's dress pants. They have a long history in men's fashion, dating back to the early 19th century.

The first slacks were called "slops" and were worn by sailors in the British Navy. They were loose-fitting and made from durable fabrics like canvas and denim. In the early 1900s, slacks began to be worn by men in everyday life as well, particularly for sports like golf and tennis.

Today, slacks are still popular and come in various styles, fabrics, and colors for a casual or business-casual look.

The different types of slacks and which ones are right for your body type

slacks vs dress pants

There are several different types of slacks available, each with its own unique characteristics that can complement different body types. Here are a few examples:

  1. Flat-front: These slacks have a smooth, flat front with no pleats, making them a great option for men with a slim or athletic build. These are an example of wide leg slacks with a flat front from Club Monaco.

  2. Pleated slacks: These pleated pants have one or more pleats at the waistline, which can provide extra room in the hip area. Pleated pants can be a good choice for men with a larger build or those who prefer a looser fit.

  3. Tapered slacks: These slacks are narrower at the ankle than at the waist, creating a modern, streamlined look. They can work well for men with a slim or average build.

  4. Wide-leg slacks: These slacks have a wider leg opening than other styles, which can be a good option for men with larger thighs or hips.

  5. Cropped slacks: These slacks are shorter in length than traditional pants and can be a great option for men who are on the shorter side.

Choose the best slacks for a formal event for your body type and consider both fit and style. Look for slacks that fit well in the waist and hip area, with the appropriate amount of room for your body type.

Additionally, consider the style of the slacks and how they will complement your overall look. A good rule of thumb is to choose slacks that balance your body proportions and enhance your best features.

Slacks vs. Dress Pants Comparison

Slacks and dress pants are often used interchangeably to describe suit pants, a type of tailored trousers worn in formal or dressy casual settings. However, some people may use the terms differ depending on the context or regional differences.

Dress pants may refer to a broader range of tailored trousers that can be worn for semi-formal events and other formal settings. They are often made from high-quality materials like wool, silk, or cashmere, and are designed to be more dressy than casual pants. Dress pants and other suit trousers may have a more tailored fit, with a higher rise and narrower leg, and are often paired with a blazer or matching suit jacket along with a pocket square or tie.

Overall, while slacks and dress pants share many similarities and are often used interchangeably, dress pants may refer to pants suitable for more formal events, while slacks may refer to a slightly more casual or versatile style of trousers.
