Size and fit can vary between different brands or even different styles. Some brands make more than one fit in things like shirts or suits.

Where a brand has provided it, we have included an individual size guide for each item. Click on the 'Size Guide' link under where you select the size you want to purchase, like this:

Size guides are approximate and for guidance only. Garments may differ slightly depending in style and fit. Measurements and sizing is based on each brand's individual guidelines and may differ from brand to brand. 

Where there isn't a size guide showing, the brand has not provided any size info. Please contact us for help with sizing in that instance.

Here is a general size guide for hats and hat size conversion:

Some styles/brands may differ. 

 

How to Measure your Head:

An average head size for a man is 57 - 59 cms. The average head size for a woman is 55 - 57 cms.

To check your head size, take a measuring tape and place it around the circumference of your head, slightly above the ears. The measurement is the size of hat you will need. eg. If you measure 57cm, your hat size is 57cm and so, a size medium.

How To Measure Your Chest Size:

Raise your arms slightly and measure just under your arms. Be sure to cross over the shoulder blades and the fullest part of the chest. Jacket sizes are equal to your chest size. For example, if you have a 38" chest, you would wear a size 38 Jacket or Coat. Be careful not to measure too tightly as your clothing will then be too tight.

If you are unable to measure yourself easily you can also compare the sizes to a jacket you already own and which fits you well. Measure the jacket laid flat and zipped or buttoned up. Measure straight across the jacket on the front from armpit to armpit, from seam to seam. Double the result and this should give you the chest size of the jacket. eg. If you measure 19" across the chest of the jacket, armpit to armpit, 19" doubled is 38", so 38" is the chest size of the jacket. Please bear in mind that different fits of different jackets may be tighter or looser cut, so it may be worthwhile measuring 2 or 3 jackets which fit you well to get a clearer idea of what size you need if you are using this method.

To confirm your jacket size, measure your waist or the waistband of a comfortable, well fitting pair of trousers or jeans and add 6 inches. eg. If you are a 30" waist usually your chest size will be about 36", or if you are a 32" waist, your chest size will be about 38", etc.

 


 

Mens Shirts, T-Shirts, Polos And Other Tops

Most men's fashion brands follow this approximate fit (in inches):

Small: 36" - 38"
Medium: 38" - 40" 
Large: 40" - 42"
XL: 42" - 44"
XXL: 44" - 46"
3XL: 46" - 48"

This is the recommend size to fit, and not the measurement of the garment.

However, fit and size can vary from brand to brand, and not all garments follow the standard size guide. Some brands also make more than one fit (ie. slim fit, regular fit or easy fit). Check the size guide per each item, found here:

14.5" collar - XS

To measure your collar size:

Place the measuring tape around the fullest part of your neck and keep the tape snug but not tight. For a comfortable fit, place 2 fingers between the tape and your neck. Round up to the next 1/2 inch.

 


 

Mens Trousers, Jeans, Flares And Drainpipes:

 

Trouser sizes are usually shown with the waist size in inches first, followed by a letter to represent the inside leg length, ie. 32R - this would be 32" waist with a 'regular' length leg. 

Sizes shown, for example, as 32W 32L stands for 32" waist with 32" inside leg

  • UK & US sizing shown in inches. 

 

To measure your waist:

Measure around your waistline where you normally wear your trousers or jeans, keeping your forefinger between your body and the measuring tape. Trousers, Jeans and Flares sizes are equal to your waist size. For example, if you have a 32" waist, you should wear a size 32" jeans or trousers.

Alternatively you can measure the waistband of a pair of trousers or jeans which are a comfortable fit. Measure around the circumference of waist band with the trousers fastened, this should give you the waist measurement.

 

Leg Length:

Where available, Jeans, Trousers and Flares are in 3 leg lengths. Unless stated otherwise, most styles will be: 

Short (S) - 30" approx
Regular (R) - 32" approx
Long (L) - 34" approx

Some styles will be slightly different. Check the size guide per brand for more info or the item description. 

 

To measure your inside leg:

Using a pair of trousers or jeans that fit you well, measure from the top of the inner trouser leg seam to the opening at the bottom of the trouser leg (the hem). The number of inches is the inseam length, rounded to the nearest half inch.
 


 

Mens Suits and Tailoring:

Usually for suits, your jacket size will be 6 inches more than your trouser size. ie. If you are a size 30" waist, your jacket size will be 36", and so on.

To measure your chest:

Raise your arms slightly and measure just under your arms. Be sure to cross over the shoulder blades and the fullest part of the chest. Suit sizes are equal to your chest size. For example, if you have a 38" chest, you would wear a size 38 suit.

To confirm your suit size, measure your waist or the waistband of a comfortable, well fitting pair of pants and add 6 inches.

To measure your waist:

Measure around your waistline where you normally wear your trousers, keeping your forefinger between your body and the measuring tape. Trousers sizes are equal to your waist size. For example, if you have a 32" waist, you should wear a size 32" trouser.

Alternatively you can measure the waistband of a pair of trousers which are a comfortable fit. Measure around the circumference of waist band with the trousers fastened, this should give you the waist measurement.
