Make sure everything is well ironed and then roll up suit trousers turn jacket inside out and fold carefully around the trousers. No one yet has called me a scruff. I don't transport a suit everyday, but have to rotate the stuff I leave in the office.
I have an Altura "suit carrier". The original design, which I have, wasn't very good, but I was recently looking at the current version in my LBS and it seems to be much better.
Having said that it has always been fine for heavier garments like suits or trousers, but I have never successfully carried a shirt without it getting all creased up.
By the way I dont think it is called a "suit carrier" which is why it may not be showing up on Google. I think it is possibly called a garment bag - but can check in my LBS if you have no luck in tracking it down.
