Size A - Collar. If you don't already know your collar size then place the measuring tape around your neck at the point where your shirt collar would sit. This size should be very loose giving yourself plenty of room to move. This size should be around 1.5 to 2 inches larger than your actual neck size.

Size B - Chest Size. Hold your arms out about 2 feet from your body, then place the tape measure around your body, just below your armpits. This size should be loose.

Size C - Arm Length. You can either measure the outside arm length from seam to cuff on a good fitting jacket that you may have or run your tape from the top of your arm down to your wrist bone.

Size D - Kilt Waist. This size should be taken over your shirt. Wrap the tape around your body at the point just above your navel, pull the tape very very tight then slacken it back until it feels comfortable but very firm. The larger the gent the more the tape will sink into the body, this is normal, for if this size is not tight enough the Kilt may start to slip down when moving around.

Size E - Kilt Drop. At the same point as the Kilt waist (size D - just above the navel) measure down to between top of the knee cap and the mid knee cap, this size will be the length of the Kilt. This size should be taken straight down and not at an angle( as show in image). 

Size F - Shoe Size. Simply the size of shoe you require.

Size H - Your Height. This is is important, this size will give us an idea of what your sizes should be and will tell us if you have measured correctly.
