There is not right or wrong way to buy Lilly Pulitzer vintage clothing.  Just buy what you love.  The wonderful thing about wearing Lilly Pulitzer vintage is that no one will be wearing what you are.  You'll never have to be afraid of running into yourself.   You know that fashion icons like Jackie Kennedy and her sister Lee, who loved Lilly, still influence Lilly's trends today.  Lilly Pulitzer even rereleases beloved older fabrics  in a neo vintage line.

However, know that only a true Lilly Pulitzer vintage piece will have "The Lilly"  label.

Shopping for vintage is just as much fun as wearing it.  It's not always easy to find the right fit or color.  Always keep in mind that sizing changed in the 1970's.  A vintage garment marked size 14 is not the same as a size 14 today.  If you are buying online, insist that the seller provide the measurements so that you can compare it to a dress you know fits you.  However, if the dress you buy is too big, a good seamstress can alter it to  make it perfect for you. 

You can easily work Lilly Pulitzer vintage into your wardrobe without looking dated.  Her prints are timeless.  The compliments you receive will be proof that you made the right choice.  When people ask where you got that fabulous dress, tell them it is one of a kind and to go on their own treasure hunt.
