Citrus hues will be hot in fashion this spring and summer.Teens and twenty-somethings can get away with the bright yellow jeans you’ll see in stores. But for the rest of us, a more grown-up take on citrus blends yellow with dusky blue. For work, pull off this spring fashion color combination by pairing a pale shell with soft blue trousers. Layer on a wooden necklace and navy blazer for a presentation-ready look. On casual days, try a bright yellow tunic cover well-fitting faded jeans, or tuck a silky yellow blouse into a soft blue.A-line skirt. Add bright turquoise jewelry or a belt in cobalt blue to finish your stylist day-off look.
