Our suits are sold in sets with the standard U.S. sizes with a 6" size drop between the jacket and pants.

We are unable to mix and match sizes and do not offer alterations for any order.

Please order based on your chest size and get the waist of the pants altered to fit by your local tailor.

The waist of our pants can be let out up to 1 1/2" or taken in up to 3" by a tailor, who can also taper in the suit and hem the pants to your desired length.
T
he sleeves can be let out up to 1".

Suits in a slim cut would have the word "slim" noted next to each size.


PLEASE READ TO FIND YOUR SIZE
98% of all people who buy a suit will need alteration. 

To ensure you have the perfect fit and look as great as you can, before you go out in your new suit, we’d recommend you find a good local tailor who can handle the standard alterations if needed.

Select suits in our collection are available in a slim cut and modern cut.

Our suits in a slim cut are very fitted and do not allow much room for alteration. Your local tailor would be able to taper in the suit to your desired fit when you order the size closest to your measurements. Before an actual alteration is made, your tailor can let you know if the adjustment would fix the fit issues. Please note that once a suit is altered, it will not be eligible for return.

Our suits are made by hand; each can vary with a 1/2" to 1" leeway in flat lay measurements.

HOW TO MEASURE YOURSELF
Please read all the instructions below to best understand how to order your desired size.

First note to keep your body loose and relax, don't flex or hold anything in when measuring yourself. 


MEASURE YOUR CHEST:
Place the tape measure beneath the armpits and just above the nipples, and place two fingers under the center of your chest, also try to make the tape measure level.

This measurement will be your jacket size.
Our model here measures at 38", so he wears size 38 jacket.

MEASURE YOUR WAIST:
Note that your natural waistline might not match the waist size of the pants you are wearing.
Wrap the tape measure around your waist—not your belly.
To find your waist, you can hold 4 fingers below belly button and below that will be your waist.
Don't let it be too loose, and don't squeeze it too tight. This measurement will be your waist size.
Our model here measures at 32" so his pants size is 32W.

MEASURE YOUR HEIGHT:
Use the range of heights below to determine if you are a Short, Regular, or Long.
Keep in mind that some people prefer the look of a longer jacket and some a shorter jacket, so these are not set in stone.
SHORT (S) 5'4" TO 5'7"
REGULAR (R) 5'8" TO 6'2"
LONG (L) 6'2 1/2" TO 6'6"
