Slacks are soft-fabric trousers built for everyday smart casual wear. Dress pants are more structured, cut for business formal and formal occasions. Both look similar on a rack. They sit differently on the body, work differently across occasions, and are made from different materials.
Not all men's trousers are the same. When shopping for a new pair of trousers, you'll need to choose the right type. There are slacks, and there are dress pants outfit. Slacks and dress pants are two of the most popular types of men's trousers. They are available in many of the same styles, as well as colors, while offering a high level of versatility.
Slacks and dress pants, however, differ in several ways. To determine which type of trousers are right for you, you'll need to familiarize yourself with their differences.
What Are Slacks?
To define slacks, they are a type of men's trousers that are characterized by a loose-fitted construction. The word "slack," in fact, was derived from the Saxon word "slak," meaning "loose." They aren't tight or snug when worn. Rather, slacks live up to their namesake by fitting loosely.
Most slack pants are made of a woolen material. Wool, as well as wool-based textiles are typically lightweight. Therefore, they allow for a loose-fitted construction. You don't have to worry about a pair of slack dress pants sticking to your body. All slack pants offer a loose-fitted construction that gives your body plenty of room in which to breathe. This loose-fitted construction is a defining characteristic of slacks.
What Are Dress Pants?
Dress pants, on the other hand, encompass a variety of types of formal and semi-formal men's dress pants. They are known as "dress pants" because they are used for "dressing up." If you're trying to create a formal or semi-formal outfit, you'll need to wear dress pants. Men's dress pants are an integral part of all formal and semi-formal outfits. The pairing of dress pants and a dress shirt epitomizes sophistication and sartorial excellence.
There are multiple types of dress pants. Chinos, for instance, are considered men's dress pants. They are made of a twill, cotton-based fabric known as chino cloth. Chinos were originally invented in the 19th century, during which they were used for military uniforms in the British and French armies. Since then, chinos have made their way into the world of civilian fashion. You can now find chino dress pants available for sale at many men's clothing stores.
In addition to chinos, suit trousers are considered men's dress pants. Suit trousers are those that are worn in a suit outfit. A two-piece suit consists of a pair of suit trouser with a matching suit jacket. Because they are formal, suit trousers are considered men's dress pants.
Differences Between Slacks and Dress Pants
One of the ways that slacks and dress pants differ is that the former features a loose-fitted construction, whereas the latter typically features a more tight-fitted construction. Slacks are designed specifically to fit loosely when worn. Rather than sitting close to your legs and body, they are more spacious.
Slacks and dress pants are often made of different materials as well. Slacks are typically made of a woolen material, which is responsible for their loose-fitted construction. Dress pants, on the other hand, are available in many other materials, such as Cotton dress pants for breathable smart casual wear, Linen pants for warm weather and resort wear, and even synthetic fabrics.
It's also worth noting that slacks, especially slack khakis, offer a more casual style than dress pants. You can still wear formal slacks in semi-formal outfits, but they aren't as a formal as dress pants. Slacks have a naturally casual appearance. Some men prefer the casual slacks over the more formal dress pants. Regardless, slacks are almost always more casual than dress pants.
