Designers must have taken their vacations in colorful lands this summer because the rainbow is back in our lives for spring. This, of course, means we get to shake things up a bit in our world of accessories. And it’s about time—fall’s camel loafers, camouflage-green boots, and ladylike neutral bags were beginning to tire me.  The color combinations vary but are all so fabulous, you may have to own more than one—better get on the wait list. There are great alternatives. The scarf is back, and we have seen it worn in a million new ways: on the head, tied tightly around the neck, Western-style. Get creative with this. Belts, sunglasses, and hats were also everywhere, so play, don’t be afraid, and smile. This is going to be a fun, vibrant summer.
