I ordered through LE custom, and it came out fine - I wanted a white fitted spread collar french cuff shirt without a pocket. Based on the measurements I gave them, they did a decent job. But I wasn't aiming for something that looks sprayed on, which sometimes I feel a lot of forumites are aiming for.
I might order again, and if I do so, I might make some tweaks, depending on how the shirt shrinks in the next couple of washes (I've only washed and worn it twice). Take in the body maybe a half inch or inch or so and shorten the sleeves a half inch. Everything else was decent.
Just remember to select the Tailored fit option, not the traditional fit option. And if you really want it fitted, take an inch off your waist size (I gave 35, but if I was ordering pants, I probably would have given them 36).
Edit: I'm 6'1" and 185-190 and a 35-36 waist, so I'm a pretty proportional, normal athletic build.
