Marc Jacobs Brown Butterfly Ladies Sunglasses MARC 791/F/S 0086/HA 57

This women's pair of sunglasses is Marc Jacobs Brown Butterfly Ladies Sunglasses MARC 791/F/S 0086/HA 57. Fit does most of the work — the arms should rest without pinching and the lenses should sit clear of your lashes. Check the fit at the bridge first: if they slide down there, no amount of arm adjustment will hold them. Discounted listings come and go, and rarely at the same shop twice. Store them in a case rather than face down, and keep them out of a hot car, which warps frames and lifts coatings. Whoever is cheapest today may not be tomorrow, so it is worth looking again before settling on the best deal.
