At the moment I'm oversaturated by the colourblocking themes. But I won't say something against the bright colours (I always liked colourful clothes, but at the moment there are more possibilitys to get them), but combine them with calm shades like nude, black and white. So wear it as pure as you can (actually I think my bangles were already to much..). Another idea I like is to wear one in one tones like I've been showing already here (click!).
