Dress Shirt Vs. Casual Shirt

Okay, men! Today’s fashion world is fraught with perilous choices. The dress shirt, sport shirt and casual shirts have all started looking very similar. While it’s obvious when to skip the t-shirt and go for a nicer buttoned shirt, it can be more difficult to navigate just how far to take the formality these days.

Never fear, this article will serve as your authoritative guide to the world of men’s fashion. What’s the difference between formal, dress, and sporty? When do you wear which look? Find out all the answers now!

Shirt Types

The first thing you need to know about is the most common types of shirts. There are formal dress shirts, casual and sporty shirts. Each one is worn on different occasions. It’s pretty easy to tell formal shirts apart but the others can get a bit confusing when it come to the rules.

The dress shirt is a fashion staple. It can be dressed down into casual looks, but it was not made for this purpose. It’s a semi-formal (business) type shirt. It’s extremely common and comes in a variety of collar and cuff types and styles. 

These are long sleeved, button up shirts. They are worn at work, during business meetings or at nicer events. Dress shirts are typically worn solo, over an undershirt, or under jackets. They are very versatile and can be worn to church, weddings, proms, and interviews. Adding a tie and jacket adds formality, but they are often worn without for a business casual look.

The sport shirt is not actually your favorite workout tee. This is a very distinctive style of shirt that originated with the Brooks Brothers and became quite popular in England. These are usually less stiff in the collar than dress shirts and they come in bolder patterns and colors.

These are great options for casual wear, turning jeans into something sharper than just jeans and a tee. These can be worn with everyday wear and don’t usually show up in the office.


A very popular variant of the sports shirt is the polo shirt. This is seen in golf and tennis sportswear.  These don’t button down all the way, but they do have a collar. They’re usually made of knits rather than woven materials, so they’re very comfortable and pretty breathable. They’re also great to wear at country clubs or in environments where you are playing sports but still need to look nice. 

How Should Your Shirt Fit?

Now that you know the difference between the 4 major type of nicer looking men’s shirts and when to wear each type, let’s make sure you know the right fit for your body. The fit of a shirt can quickly make even the most formal shirt look sloppy or make the casual ones look sharp and on point.


The 2 basic measurements for men’s dress shirts are the neck and sleeve sizes. These measure the length you need. The fits come in inches or European fits. For help transitioning, an American 15’’ neck is around a 38 in European sizing.  Casual and sporty shirts tend to come in standardized S, M, L, XL sizing.

You want your collar to be tight but not to choke you or restrict airways. Remember, that in dress situations you will be adding a tier. Your sleeve length should come anywhere from just above your wrist to just at your wrist. It should never extend past the meaty part of your hand and into your palm. 

The exception to longer cuffs is in a more casual look, where you fold the cuff over a jacket or sweater sleeve. 


The length is going to make a big difference in telling the difference between dressy shirts and casual ones. Dress shirts are made longer because they’re meant to be tucked into pants. They need to have some length to allow you to move or dance without coming untucked.

Sporty and casual shirts have lower side seams and the shirttail is shorter, so that you can wear them untucked without looking like you’ve donned your girlfriend’s dress. An untucked shirt should never extend lower than the bottom of your back pocket. If it’s much shorter than the middle of that same picket, you may end up showing some midriff if you move a lot.


The frame of your shirt shouldn’t change much between dress and sports shirts. It should offer plenty of room for you to stretch your back and shoulders and raise your arms. It should taper into your torso while sticking close to the hips (but not so close it’s ski tight). 

You want your final button to close on your shirt without any gaps in the buttons or constraint to your hips, but you don’t want the shirt to be so loose that you are drowning in it and lose your shape. Basically, your shirt should conform to your natural body size without hugging it so tight you’re popping out of it. 

Modern fit shirts tend to be tapered in more and work well on slim bodies. They curve inwards with your figure. A traditional fit will have a more straight down cut to it, able to accommodate rounder body types thanks to the extra room in the torso. 

Try a few different cuts to see which one best suits your figure, but remember that all shirts are cut differently so they may not be the same fit from brand to brand. Use caution when it comes to the traditional cut because they can be like pillowcases – boxy and billowy. If that’s what your shirt looks like on you, then change it quickly!! 


The fabric of a shirt can indicate quickly what type of shirt it is. Things like the material, the color, and the patterning can quickly take a shirt from formal to casual and vice versa regardless of the cut.

Dress Shirts

Dress shirts usually have tightly woven cotton or silk in very high thread counts. They are woven in forms like twill, oxford, broadcloth, and pinpoint designs. These are the ways the fabrics are woven into the shirt, with the most common dress shirt being an oxford and the quickly emerging modern fashion favorite being twill. 

These types of shirts may be a bit shiny. This adds to the dressy appearance, giving them a way to stand out from the matte design of casual shirts.

Colors in dress shirts are usually understated. They range from white to black, but are almost always a solid color that isn’t too bright. Think white, grey, black, and navy. After this, the most common popular colors tend to be pastels – soft and understated. Lighter blues, pinks, and greens. 

Dressier shirts are occasionally found in bright jewel tones, but in general the flashy color can quickly send a shirt into the casual spectrum of looks unless you know exactly how to tone the bright colors down and make them more formal with darker jackets and formal ties. 

The exception to a plain pattern is a very subtle floral. The bolder floral patterns are casual, but a small floral or paisley pattern in a pastel color can often be found in dress shirts, especially in European fashion. 

Dress shirts can also be striped, but this is rare and there are rules. The stripes must be vertical. Horizontal stripes are casual by nature. They also have to be thin. Thicker stripes are for casual shirts. Most dress shirt stripes are less than half a centimeter thick. 

The color should match without being too bold a contrast. Generally, a white shirt and very light blue shirt are the only 2 colors that you will see with stripes. White and navy is a common stripe combination. 

Casual Shirts

With casual shirts, the weaves can be more rugged. These can come in plain oxford, linen, chambray, or even flannel and denim. These materials tend to be more breathable, easier to come by, and less glossy and stuff. They’ll be more relaxed materials that are less crisp and ironed.

If a shirt is plaid or checkered, then it is almost certainly a sport or casual shirt. If the shirt is short sleeved, even if it has buttons, it is a casual shirt. If it has more than 1 pocket… you guessed it! That’s a casual shirt.

These shirts are great for layering, and will often be mixed with tees and cardigans. They can be worn on their own and will look good tucked or untucked. They’re extremely versatile.

These can come in pastels and plain colors, but typically the casual shirt is where you will find much bolder colors and patterns Checkers and plaids are common, but so are large floral patterns, printed designs, diamonds, and more. 

Pairing Combination

As a final word, remember that just because a shirt qualifies as a dress shirt does not make it dressy. If you are in a situation that requires formal dress, but you wear an untucked dress shirt with jeans and an unbuttoned collar, you may as well be wearing tennis shoes and an undershirt. This may be a great look, but it negates the dress factor.

The rest of your outfit makes a huge impact on whether your shirt is perceived as dressy or casual. Make sure that if you’re in a formal situation, you’re tucking in the shirt, belting the pants, and pairing a fitted jacket or blazer with some dress loafers. 

If you’re in a casual situation but you still want to look stylish and stand out from the crowd, pairing your dress shirt with some dark wash fitted jeans, flat sneakers, and a cardigan or lighter colored blazer will do wonders to tone it down and turn it into a casual shirt.
