Bugout Business Garment Bag

its a bit pricey but build quality seems reasonable and it works pretty well for getting your suit, shirt and trousers around uncreased especially when traveling to interviews etc on the train.
i like the fact that theres a compartment on the rucksack back for securely stowing valuables and also a large inner mesh pocket on the inside where it folds for securely stowing a netbook, tablet or laptop. this means you can carry it on the underground on your back without having to worry about things getting stolen from accessible pockets/compartments. theres also enough space in the other compartments for lunchbox, 1.5litre sigg bottle and other things.
