Errands, coffee, a school thing
Saturday shirt. Errands, coffee with my dad, a kid's party. Worked for all of it.

Passed my True Classics in a week
Had a stack of True Classics. This fits better and outlasts them, wash for wash.

5'10 average build, medium is right
5'10, 175, the guy every size chart claims to be built for and never is. Mediums are usually tight at the shoulders or tents at the waist, pick your poison. This one actually matches its own chart, shoulders sit at the seam, body falls straight without clinging, sleeves hit where sleeves should. Washed it five or six times, still matches the chart. I keep waiting for the catch and there is not one. Boring in the best way.

Nine months and counting
Bought my first one back in September. Wore it at least once a week since then. Washed it probably thirty five times and it still looks and fits the same. No fading, no stretching in the collar or body. Grabbed two more because of that. Hard to find a shirt that doesn't fall apart in six months.

Sits flat under my dress shirt
I wear button downs every day for work and every undershirt I've had bunches up around the waist or rides up in the back by lunchtime. This one stays flat. Wore it under a fitted dress shirt for ten hours and it didn't move. The length is right (hits just below the belt line without extra fabric) and the shoulders don't add bulk. Finally found one that works as a real undershirt and not just a tee I'm forcing to work.
