Simple feminine tones, with lots of bird and spring motifs are great for a sunny day. It's elegant, yet playful. I wore this with a slip underneath in Winter, to keep warm (these are absolutely amazing, really great thermal wear). Jewellery was kept sophisticated and matching, simple pearl inspired earrings and bracelets.
One 'philosophy' by the oh-so-fabulous Coco Chanel has always stuck by me, I always take off one item of jewellery before I leave the house so that I'm not overdoing it. I'm a sucker for stacks of bracelets, earrings, necklaces etc. You name it, and I'll have it on me. Flock it, let's keep things minimal!
