Pants:  There are a few questions that need to be answered before choosing a size and they are-

What is your inseam size? This is the length of the leg of your pants.  Most retailers only offer inseams down to 30 inches so you have never really seen sizes that are made for you (without tailoring).  See below to find your inseam.

Measuring:  Using a pair of pants that have been tailored and fits you correctly, take a tape measure and starting at the center seam at the crotch, measure the length of the pant leg.

If you do not have a pair of pants that fit you correctly, put on a pair of pants and flip the cuff up to your desired length. Then take off the pants and measure the length of the cuff you flipped. Subtract that number from the pant's length size. For example, if you put on pants with a 30" inseam and you flipped the cuff up 3 inches, order the 27" inch inseam length from Under 510. 

Don’t Want to Measure Your Inseam?  Use our SUGGESTED sizing:

 Up to 5’4"
26” inseam 
5’5”-5’7”
27” inseam
5’8”
28” inseam
5’9”
29” inseam

 

What is your waist size? If you aren’t sure, you can take a tape measure and wrap it around your waistline where you normally wear your pants. Subtract 4 inches from that measurement to get your pant waist size.  

Pant Sizing Variations:  Since all fabrics will fit differently on our bodies, we recommend the following sizing adjustments for each of our pants.

Jon: Runs slimmer than our other pants. Our recommendation: For thin builds, order your normal waist size. For average or athletic builds, size up one waist size. If you are brawny, size up two waist sizes. 

Bruce: Consistent with our typical fit and runs true to size. Our recommendation: For thin, average, athletic builds, buy your normal waist size. For brawny builds, size up 1 waist size. 

Kingston: Consistent with our typical fit but has extreme stretch fabric. Our recommendation: For slim and average builds, size down on the waist. For athletic builds, order your normal size. If between sizes, size down. For brawny builds, order normal size. If between sizes, size up. 

Simon: Consistent with our typical fit with only a hint of stretch. For all builds, order your normal waist size.  

Getaway: Runs Slimmer on the leg. For slim and average builds order your normal waist size. For athletic and brawny builds size up on the waist. If between sizes, size up on all builds. 

 

Shirts

Our shirts are sized to fit a shorter man properly. We designed our shirts to fit and feel like a custom tailored shirt. The shirts are made and proportioned specifically for men under 5'10. Our cut is narrower through the shoulders, slimmer through the torso, and shorter overall in length.
