Hello Chictopians, I have a dilemma that hopefully someone can solve. I recently purchased an adorable yellow Marc by Marc Jacobs pima cotton sweater from Buffalo Exchange. Normally I am not one to fuss over washing new clothes, but this is technically not new and therefore needing wash. Anyway, it says to hand wash, but do I use soap? What kind do I use if I do? Please help me figure out this hand washing pima cotton business so I can give the sweater its well deserved wear.
