I just bought a navy jersey blazer (boden) it is very nice and fits well. Apart from stripey (breton) top, what do you wear with yours? I am looking for inspiration so I actually wear the jacket as opposed to leaving it hanging in the wardrobe 
I have jeans, skinny cargos, denim skirt etc so more tops I am thinking of..Oh..I am size 10 on top and don't look good in vest tops (too pale and scrawney looknig)!
