how do you do it without creasing a suit?

Wear it 🙂 – I went to an interview once which was across town (8pm) at rush hour – just rode carefully and at easy pace. Locked my bike up outside reception walked in and left with a job – hr especially liked it when they asked me if I was claiming travel expenses for the journey and I said no I arrived by bicycle – that raised an eyebrow as she read out the address on my application form – a town some 50 miles away haha
