I purchased an Azur Speedy 25 one year ago and I am afraid to use it! It is packed away in my closet waiting for "the perfect day." Two things bother me (despite how much I love it) - 1. The vachetta changing colour when it patinas 2. Getting it dirty Now I am wondering if I should sell and purchase an Epi Speedy - ivory? Which is cuter and what should I Do!!!???
