This may seem silly in depths of winter (or is it spring? can't tell anymore) but a big bright flower clipped near a bun always makes me happy. Here is a tutorial to make some yourself it's easy, fun, cheap and you can make them exactly like you want them. A bright nail polish and matching lipstick instantly makes me feel put together. If your hair doesn't cooperate a big handband, snood (I've seen also them with shiney paillettes, easy to attach some to an existing snood) or a fun hat or beanie.
