My style: Jones Lang LaSalle boss Guy Grainger
The UK CEO of property services firm Jones Lang LaSalle likes to be sharp of suit - unless he's doing a triathlon in his Batman outfit. Here are a few things he can't do without.

Work
Because I have a background in retail property, I am hooked on shopping. I think if you're going to wear a suit, it should be well tailored - so I go to shops like Richard James or Susannah Hall, a tailor in Shoreditch. I like to keep as sharp as possible: it reflects my approach to business, I suppose.
My wife always takes the mick out of me because I wear very bland ties - I bought one at the weekend from John Varvatos, which is quite an edgy brand. When I'm at home in Muswell Hill at the weekends, I dress really, really casual.
I'm either really smart or completely the opposite. I love coffee, but working in London has made me a real coffee snob: so many great independents are emerging. An Ottolenghi's has opened near our office, which is great.
