The uniform post (now strangely locked) was about wearing the schooliform in the period running up to the test, to inspire confidence...
It was probably locked for the usual reason, as soon as a female posts anything on the internet, almost every male in the area turns into a drooling little 16 year old, with replies as such.
On the actual topic, I'd say if you have any interest in flying commercially, yes, go for the uniform. You'll feel pretty damn self-conscious (even a little silly) the first time you put it on - but it has to happen sometime.
And there are a few people around that think wearing epaulettes etc. is a load of garbage, in training or commercial ops - I don't agree. As others have said it puts you in the right professional frame of mind, as as far as pax go when you're actually flying commercially, in their minds, when walking out to the aircraft, your abilities as a pilot come down to one thing, and that's your presentation (both personality-wise, and physically). Later on in the flight, how well you grease it on forms the second part of their opinion.
