Whether you’re going out to dinner with your partner’s parents, or you’re headed out to a formal event, you want to look your absolute best. For casual outings you can toss on a nice pair of jeans and a button-down shirt, but without a suit jacket, you’ll look a little plain.

How many suit jackets do you own? Do you just have one that you wear all the time? Perhaps you don’t have any and you’re just starting to think about getting some. Instead of relying on one suit jacket, here are some reasons to own several.

1. You can wear a suit jacket with jeans

Have you ever seen someone wearing a suit jacket over a pair of jeans? It’s quite common and it’s a nice blend of casual and formal. Most of the time, people wear a dress shirt underneath, but some wear a solid-colored turtleneck or a polo. The more suit jackets you have, the more styles you can create from your existing wardrobe without having to buy multiple pairs of dress pants.

It really doesn’t matter what you wear under your suit jacket with jeans as long as your colors match and you feel confident about what you’re wearing. You don’t have to follow traditional fashion standards at all if that doesn’t appeal to you. Plenty of people make up their own rules for fashion and incorporate items like suit jackets into the most interesting outfits.

2. Suit jackets can be casual

Traditionally, suit jackets have a formal reputation and are worn with slacks and dress shoes. However, wearing a suit jacket doesn’t have to be a formal affair. There is an art form to rocking a suit jacket with casualwear, and when you get it right you’ll look stunning.

For example, you can combine a cardigan, a t-shirt, or a dress shirt. You can wear a tie or a bow-tie if you like, and yet it will always be the suit jacket that will determine your overall aesthetic. This is why you need multiple suit jackets. All it takes to jazz up your look is a few different jacket styles and you’ve got multiple looks without having to buy entire outfits.

3. You can find loud, fun suit jackets

If you’re someone who loves to make bold statements with your attire, rest assured, you can do that with suit jackets. This is one of the best reasons to get more of these into your wardrobe.

Whether you’re trying to play a prank on a friend, embarrass your friends when you go out to dinner, or just express yourself in fun ways, loud, novelty suit jackets will give you all the thrills you’re looking for.

There are novelty suits for just about every pop culture genre and fandom you can imagine, from comic book heroes and villains to sitcom characters and internet memes.

4. You might get invited to a formal event

Chances are, you’ll be invited to a formal event at some point in your life. If all you have are more casual suit jackets, or suit jackets with patterns or colors that wouldn’t work for a formal event (like a wedding), it’s time to add to your collection.

You want to be ready for the potential of being invited to a formal event, and unless you have at least one appropriate suit jacket you might not be able to attend. Most formal events have specific dress codes that have specific color requirements. Usually, those requirements are either black or white, so you can play it safe by getting one suit jacket in each color.

5. You gain/lose weight frequently

If you are someone who gains or loses weight frequently, it will help to own multiple suit jackets in different sizes. If this does apply to you, you know how frustrating it can be to have a favorite clothing item that’s either too tight or too loose and there’s nothing you can do because it won’t look right.

Get your favorite suit jackets in at least two different sizes so that you’ll always have your preferred attire, no matter how your weight is fluctuating currently.

A suit jacket collection will change your life

Whether you’re looking for more style, class, or fun, you’ll love having multiple suit jackets in your closet. More suit jackets means more options when you get invited to an event or when you’re just trying to choose an outfit for a casual outing with friends.
