The Difference Between a Slim and Regular Fit Shirt The difference between a regular and slim fit shirt might not seem like much, but it is more than enough to keep people off the racks of traditional dress shirts and heading over to the extra slim fit side. The subtle differences between the two are worth noting before heading out to pick up a few new dress shirts. The Sides When comparing the two different styles of shirts, most notice that one of the primary differences between the two is the sides of the shirt. Regular fit shirts often have a side that goes straight down. Slim fit shirts have a side that goes in slightly in a moon shape. The difference in the shape of the sides makes the slim fit shirt ideal for men that have a narrow, or skinny, waistline. When these men wear a regular fitting shirt, it often billows at the waistline even if it is tucked in. This results in them having a muffin top because of the extra fabric. Sleeves In slim fit dress shirts, the sleeves are tighter than they are in regular fit shirts. Just like the rest of the extra slim fit shirt, they are specially designed to fit a slender frame. This makes them less than ideal for individuals that like to work out or those with naturally bulky arms. If the waist is slender but the arms are on the larger side, a regular fit or muscle fit dress shirt would be a better idea. More Room to Move Regular fit shirts are designed to have a little bit more space inside, which makes them great for people that do not want to feel restricted by their movements. When a regular sized guy tries to fit into a slim fit white shirt, it usually does not end well. These shirts are intended for those that fall into the skinny category, not the average category. Instead, opt for a regular fitting dress shirt to make sure that there is plenty of room to move. Try Them Both On Sometimes, an average person can fall into the skinny category and will be more comfortable in an extra slim fit dress shirt. Other times, he will feel more at ease when wearing a regular fit shirt. Because of this, it is important to try on both styles of shirts. Do not simply button them and look in the mirror. Instead, try on the shirt and move around in the dressing room to ensure that the white slim fit shirt feels as good as it looks. Visit a Tailor Those that are not sure are encouraged to visit their tailor. Your personal tailor will know your body type, and which shirt will highlight it best. While you are there, ask them for a few measurements. This will ensure that any shirt you select will look amazing and fit perfectly. Those that want to buy a shirt off the rack instead of a custom shirt can still opt for measurements so that they know what to look for in a dress shirt. There are only a few differences between these two styles of shirts, but those differences are significant enough that a person should know which one will suit their body best before buying it.
