By day/in business this shirt can be tucked in, buttons on the barrel cuffs closed, spread collar looking sharp & crisp. By evening/casual (really anytime of day) this shirt can be unbuttoned to reveal silky smooth lining at the collar and at the rolled back cuffs. Untucked, of course. Pearlized buttons that have been dyed to match the fabric offer a subtle detail that keeps it simple & elegant but not so delicate to not stand up to wash & wear. A classic button-up for the modern man... who can surprise us with his own unique strength & versatility just like The Trotter will.

Fit & Fabric

A classic, casual fit offering more room in the shoulders, chest, and arms than Semi-Fitted. Slightly tapered to the waist (prevents billowing when the shirt is tucked in) creating a slimmer look than our Relaxed Fit without having the close-to-the-body cut & feel as our Fitted cut. Sleeves are marginally boxier. This cut is timeless & spans generations (meaning it’s been around for a long time — think of your father or grandfather, why it’s a “classic” fit) for those who lean more towards comfort over fashion.

  • Innovative, exclusive fabric featuring Lyocell. Eco-friendly from sustainably grown forests.
  • Superior color richness & retention that resists fading after multiple washes.
  • Ultra soft hand revealed in the smooth finish and overall feel.
  • Just the right stretch to move with you.
  • Versatile style that looks great either tucked or untucked.
  • Breathable, absorbent, moisture wicking, antimicrobial and works hard to resist wrinkles.
  • Machine Washable.

Measuring Guide

With a tape measure, find your body measurements below to find which size is likely for you. To speak with a sizing expert, email us.


With your elbows raises, wrap your measuring tape around your chest, just below your armpits. Then, drop your elbows to your side. You are going for the largest part of your chest.

Sleeve (arm length)

Bend your elbow 90 degrees and place your hand on your hip. Hold the end of the measuring tape at the center back of your neck. Then, place your fist on your waist. Run measuring tape over your shoulder and elbow and down to the ball on the outside of your wrist. The total length is your arm length. 


Measure around the middle of your neck (at the Adam’s apple), keeping tape a bit loose.


Measure around your natural waistline about a couple of inches below your belly button, keeping the measuring tape a bit loose. Make sure you don’t suck in or hold your breath. Keep in natural.
