Layering is key! And keep layers light. That way you're able to change up your outfit and feel comfortable in this unreliable weather.
I'm not one of those people who keeps two different closets organised by season. It doesn't matter if its rain or shine, my sunglasses will be worn! I will always use the wind for an excuse to wear any leather and my colour pallet won't change according to season.
If I want to change it up for the summer, I'll just apply some bright lippy (Chanel No 36), put on a pair of fabulous sandals and most importantly - Just have fun with it all!
