Would you trust a doctor in a T-shirt?

If one means that a lawyer acting against one on behalf of another party cannot be trusted, well, of course. Such a lawyer is not acting for one. In that instance, one would instruct one's own lawyer, and that lawyer would be 100% trust-able.

Not exactly a common occurrance admittedly, but amusing you say that given the drama over this the past week.
We all "know" iffy examples. Doesn't make it general fact. Unless of course we have some stats that show lawyers are generally more self serving than any other walk of life. Do we?
I suspect the same could be true with long sleeves.
If they merely want to look more romantically attractive in the suit, then it's meaningless in evaluating them as programmers.
If they're signaling conformity to management, then that may impact my goals, pro or con. If they're contracting at a conservative bank, that's a smart thing. In other situations, they may conflict with my goals.
So, these little details may provide topics for further, brief investigation. In much the same way that, when you first walk into an office, you see indications of the power structure. (For instance, is one seat uniquely positioned to easily see what's going on in all the other screens?)
This is, as others here have pointed out, more generally a question of conformity (with some arbitrarily expected "norm").
[1] An example off the top of my head: I'd question the competence of a fire-fighter turning up to fight a fire in jeans and a t-shirt instead of proper protective attire.
As you should, a fire-fighter's protective bunker gear is necessary to perform their job function.
A coat or tie OTOH does nothing to improve the doctor's ability to perform his/her job function. Deference to such traditional costumes might even lend credibility where none is deserved.
