My uncle is taking me to a jazz concert while I visit him. I'm stumped as to what to wear. My opera capsule dresses are probably far too formal. I have a silk short sleeved leopard shirt dress or a black silk and mesh shirtdress that I could throw a light jacket over. I did pack my black Helmut Lang maxi dress, but that looks best with sandals and the actual day of the concert is going to be on cool side.
