I used to have the same problem with white jeans every year until now..... I used to wait until April or May to get my summer whites, but found that the selection was quite low. You see, all the good styles are available now, and they won't be around for long. Savvy shoppers (like me finally) will buy them up in triples, so do not wait. Check out The Gap, Banana Republic, J.Crew, Etcetera www.etcetera.com, Macy's or Dillard's.
White jeans are so flattering, even for those women who have more ample hips and bottoms. There is a sleekness to them, and I even believe they can be worn well during wintertime!
Live in color!
