Formal is the new casual

Last Saturday I had the pleasure of sharing a great lunch and an even better chat with Giulia and her mum. Of course it was a casual rendez-vous and all but when one knows that the women sitting across the table look extremely chic in pretty much anything one has to make an effort to look presentable. And so I went for the famous casual chic, which for me is some sort of middle ground between a classic smart combo and its opposite. I paired up a tiny blue and black gingham shirt (H&M) with a bottle green crew neck jumper (Uniqlo) and my favourite double-chested navy blazer from Zara. The casual touch was introduced by the blazer's jersey, my classic-coloured Cheap Monday jeans and my indigo blue lace up Vans. Thoughts?

PS. Apologies for the bad quality of the picture. I took it with my blackberry and I had to alter the brightness so you could kind of see the jumper was actually green.
