As a dude who is 6’ 1” or thereabouts with a 32” or thereabouts waist and a 34” (or thereabouts) inseam: can confirm.

Carhartts size up a waist size to account for shrinking, and I can almost reliably find a 34/34. Finding 32/34 in other pants is a challenge. On the subject of vanity sizing, I’m 15 pounds heavier than I was 20 years ago, and I still wear a 32/34. Which is why all those measurements are qualified above.

Finding shirts that fit is a similar challenge. Fitted shirts can usually be found in 16 34-35 with an athletic cut. Letter sizes are a total crapshoot. Sometimes I’m a L, sometimes an M. If I’m an M across the gut, frequently the shoulders are far too tight.

Not that I’m complaining as such, but I do agree that the sizes encompass too little information about body shape.

I'm 6'0 34/32 and even still feel some of this; L shirts are baggy, but M shirts (and sweaters) are often too short in the length and arms, especially after a wash.

And it's not my imagination; I have a few custom made dress shirts from Maxwell's and those absolutely do feel correct in both dimensions.

A tall medium where available will typically work for me but most brands don't have it at all and those that do it's a special order so what's even the point of being in the store; I might add well have just done a blind buy online from home.

As a dude who is 6'7" with a 35" waist (34" in brands that do vanity sizing) and an inseam that can handle a 34" even if it's not quite long enough, I agree that it's tough. One of the more annoying problems is that the MT shirt size doesn't seem to exist where I shop and LT flares outwards at the bottom. At least it's pretty easy to get a shirt taken in.

For work casual (and formal!), I was thrilled to discover tailored shirts. Not bespoke, but actually getting fitted in a store like Jos. Bank that handles the alterations.

The value proposition is comfort and they last a decade.
