I use a backpack everyday for work but on a Monday I neatly fold my suit and put it in a tank bag with nothing else in the tank bag and still use my backpack for everything else. I then leave my suit in work until Friday when I use the tank bag to bring it back. I fold my shirt everyday and put it in my backpack behind my laptop so it sits nicely between my back and laptop and therefore doesnt crease. I have a pair of shoes I leave at work. I wouldnt consider wearing any of my work clothes to work because if you get a day anywhere near as hot as Monday by the time you get there you will look like you have just jumped into a swimming pool fully clothed.
