How It Works
First Fitting and Style Consultation
After booking your appointment online, you'll visit with our local staff. We'll take your measurements and review fabric and style options.
In about 4-6 weeks, your suit will be complete with the exception of the sleeves and pant length. We'll invite you back to finalize your fit and determine any minor fit adjustments.
Perfect Fit for Life
A few weeks later, we'll finish your suit. Your final measurements will be saved in our systems for simple reordering.

Made in the legendary Southwick factory
We're proud to partner with Southwick, an American suitmaking institution that has been making suits in Massachusetts for over 85 years. Their focus on craftsmanship and classic American style is the perfect complement to our ethos at Ratio. Southwick employs over 300 skilled operators and is one of the few remaining suit factories in the US.
Our core suiting range covering comes from the legendary Italian mill, Vitale Barberis Canonico, which has been weaving fine suiting fabrics and remained family-owned for 15 generations. Or, if you're feeling adventurous, choose from an extensive collection of fabrics from cottons, to tweeds, to the finest Loro Piana cashmere.
Custom Details, Superior Construction
All the details you've come to expect in custom suiting are available.
- Choose from a variety of available lapels, pocket styles, linings, and buttons
- Optional pick-stitched edges and functional sleeve buttons
- Half-canvas standard; Full floating horsehair canvas available
Guaranteed Perfect Fit
Our signature Ratio model features a natural shoulder, high armhole, and a modern jacket length. We also offer a classic fit model if you prefer a more generous cut or traditional styling.
We'll work with you to make sure you're 100% satisfied with the fit of your suit and alterations on your first suit are complimentary.

Perfect Rating on Yelp and Google
“Once again, another perfect shirt. I have tried other custom shirt companies. They were all inferior. I continue to buy Ratio shirts because the fit is always perfect and the materials are outstanding.”
“This is my tenth shirt from Ratio—and I continue to love their high quality and reliability. It's always my first stop for shirts.”
“Absolutely perfect, from the customized sizing system, to the quality of the materials, to the selection of patterns and design options, to the price point.”

What are your prices?
All prices include standard customization options, though some options will incur additional cost. The starting price for each garment category includes most of our fabric range.
How long does it take?
First-time customers require two fittings and a total time of about 8 weeks for a finished suit. The second fitting with a nearly completed garment takes place 4-6 weeks after the first fitting.
Once your size is finalized, new suit orders take 4-6 weeks and do not require a fitting.
Don't forget shirts
We've built our national reputation through our custom dress shirts. Each shirt is handmade and constructed in the U.S. using the best fabrics from the top mills in the world.
While being fitted for a suit, you'll have the option to be fitted for shirts as well.
