Don’t worry about shrinkage — we’ll account for that automatically based on fabric choice. You can fine-tune your collar size down to 0.1” or adjust any of the 16 other customizable size parameters when you create a custom size.
Sleeve length is measured from the center back to the edge of the shoulder and down to the end of the cuff. Fine-tune your sleeve length down to 0.1” or adjust any of the 16 other customizable size parameters when you create a custom size.
Slim Fit will be nicely fitted, yet comfortable. Super Slim Fit is for those that prefer a particularly trim fit and are not bothered by slight tightness or limited range of motion. Classic Fit is a more generous, roomy fit that won’t hug the body closely.

The first non-iron shirt was sold 60 years ago and has since been a mainstay in the working man's wardrobe. We worked with the world's most highly regarded mill, Thomas Mason, to bring the non-iron shirt to a whole new level in quality. Woven from premium American Supima and Egyptian Giza cotton and finished in Thomas Mason's state-of-the-art facilities. This is part of the first collection of non-iron fabrics Thomas Mason has ever made.
This 100s 2-ply fine twill is made from the best American Supima cotton that gives it a particularly soft hand and great strength. We love how it's a medium-weight 100s 2-ply, which means it wears comfortably all year round with great durability thanks to the double twisted yarn. Finished with an innovative nearly formaldehyde-free treatment to stay wrinkle-free throughout the day, while still wearing comfortably against your skin. It's also a breeze to care for. Wear it straight from the washer and dryer, or give it quick press for an incredibly clean and professional look. Opt for the President Spread if you’re planning on wearing it with suit and tie, or go Semi Spread for a more conservative look. Learn more about Thomas Mason Non-Iron Shirts here.

How do I get started?
First, welcome to Proper Cloth. We specialize in custom dress shirts, suits, jackets and pants.
The first step would be to create a size using our Smart Size Quiz. We’ll use your answers and data from thousands of satisfied customers to generate custom dress shirt sizes in your account.
To order, you can browse our gallery of curated, pre-styled options and purchase them, made to order in your custom size (and style, just click ‘Customize’ to modify).
You can use our Design-A-Shirt tool to create a custom designed shirt from scratch, selecting the fabric and all style details (collar, pocket, buttons, etc), before applying your custom size! We highly recommend only getting one shirt to start so we can lock down the Perfect Fit (Guaranteed!).
How long does it take to have a custom shirt made?
Standard finish, casual wash, and non-iron shirts generally take 12 to 14 days to produce and deliver. In all cases, the promised delivery date range at checkout should be accurate (if not slightly conservative). Click here to see our typical delivery times based on product.
Orders including shirts with Mother of Pearl buttons (Mother of Pearl, Tall Mother of Pearl, or Australian MOP) must undergo special Fish and Wildlife inspections that may cause delays. For this reason, the expected delivery date range will be extended by an additional 14 days.
Can I change the collar or cuff style? Can I add a pocket? Short sleeves? etc.
As a made-to-measure shirtmaker, we offer a wide variety of style features. Proper Cloth shirts can be styled with any of our 30+ different collar styles, 12 different cuff styles, and one of our 9 different pocket options can absolutely be added.
Just click the 'Customize' button next to any of our pre-designed, photographed shirts to edit the design however you wish!
Short Sleeve shirts can be ordered by specifying as such under the Cuff/Sleeve section of the Design-A-Shirt tool.
Do you offer rush delivery?
Rush delivery is not available for custom made products. With ready-to-wear and stocked products, we have a little more flexibility.
