The biggest reason people avoid buying online is the fear of getting the wrong size.


Many people hesitate before ordering a shirt because they do not know if it will fit their body or not, especially with the difference in sizes between brands.


In this quick guide you will learn the correct way to measure a shirt, and how to compare the measurements to the size chart to confidently order the shirt that fits you perfectly.


How to measure your size in just 3 steps?


Choosing the right size starts with three simple measurements that can be taken in just one minute.

All you need is a measuring tape and a shirt that actually fits you to compare it to.



1) Chest measurement

Lay the shirt flat on a level surface, then measure the distance from one armpit to the other in a straight line.

This measurement is the most important because it determines how comfortable the shirt is on the body.



2) Shoulder measurement

Measure the distance from one shoulder end to the other shoulder end across the top of the shirt.

This measurement determines how the shirt will sit on the shoulders, which is an important factor in the overall appearance.



3) Measure the length of the shirt

Measure from the top of the shoulder next to the collar to the bottom end of the shirt.

This measurement helps you determine if the shirt length is suitable for your style of dress, whether tucked into pants or tucked out.



With just these three measurements, you can compare the numbers with the store's size chart and confidently choose the size closest to you, increasing the likelihood that the shirt will fit perfectly the first time.


Delmere Shirt Size Chart


To make it easier to choose the right size, Delamere shirts rely on a clear size chart based on two basic measurements: width and length .


The width is measured from under the armpit to the armpit, while the length is measured from the top of the shoulder to the end of the shirt, as I mentioned to you.


The following is the approved size chart for Delamere shirts:


  • S: Width 53 cm – Length 73.5 cm
  • M: Width 55 cm – Length 75 cm
  • L: Width 57 cm – Length 76.5 cm
  • XL: Width 62 cm – Length 79.5 cm
  • XXL: Width 64 cm – Length 79.5 cm


For the best result, compare the measurements of a shirt that already fits you with this chart, then choose the closest size.

This way, the chances of getting the shirt in the correct size the first time are increased.


Does linen stretch after washing?


This is important information that should be known before choosing the size.


Natural linen does not stretch like synthetic fabrics, so it cannot be relied upon to expand after use.


Conversely, very slight shrinkage may occur after the first wash if it is washed at a high temperature.


But in most good linen shirts the fabric is pre-treated to reduce this shrinkage, so the size remains fairly consistent with use and washing.


What does that mean when choosing a size?


It is best to choose a size that provides slight comfort in the chest and shoulders rather than a completely tight size, because linen is designed to be comfortable and allow natural movement, not tight on the body.


Tip: Should you wear Slim Fit or Regular Fit?


Choosing the type of cut for the shirt is just as important as choosing the size itself.


The two most common styles are Slim Fit and Regular Fit, and the difference between them depends mainly on body shape and preferred style of dress.


The Difference Between a Slim and Regular Fit Shirt


When should you choose Slim Fit?


Choose Slim Fit if your body type is:


  • Slim or athletic
  • Your shoulders are defined and your waist is narrow.
  • She prefers a modern, close-fitting look.


This type is slightly tight at the chest and waist, and gives a stylish and body-defining appearance.


When should you choose Regular Fit?


Choose Regular Fit if your body type:


  • Medium or slightly full
  • She prefers comfort and movement more
  • The shirt is suitable for travel or everyday use.


This type provides more space in the chest and waist, so it is more comfortable and flexible, especially in linen shirts.


In linen shirts specifically, many men prefer Regular Fit because it provides better ventilation and a natural feel during movement.


What do you do if you ordered and received the wrong size?


Even when following the steps for choosing the size carefully, it may sometimes happen that the shirt arrives in an unsuitable size.


The good news is that authorized retailers like Delmere offer exchange or return options in this case, giving you greater peace of mind when buying online.


If the size is not suitable, you can simply request to exchange the product for another size or return it according to the store's approved policy.


You can check the exchange and return policy page in the Delmir store where you will find all the details and how to easily place an order.


Should I choose the size according to my body or according to a shirt I own?


It is always best to rely on the measurements of a shirt that actually fits you and compare it to the size chart.

This method is much more accurate than direct measurement of the body.


What should I do if I'm between two sizes?


If your measurements fall between two sizes, it is best to choose the slightly larger size, especially for linen shirts which are supposed to be comfortable and not tight.


Do sizes differ between brands?


Yes, sizes may vary from brand to brand, so it is always important to check each store's size chart rather than relying on the size you usually wear.


Does body height affect size selection?


Yes, taller people often need a longer shirt so that it fits properly when moving or when worn outside of pants.


Are linen shirts tight or comfortable?


Linen shirts are usually designed to be comfortable and breathable, so many people prefer to choose a size that provides a little room for movement rather than a very tight size.
