The Marc by Marc Jacobs Simone striped silk dress (originally mentioned here) is gorgeous for a casual day of fun in the sun, and the bright stripes give it a very beachy feel. This little number caused such a stir that it is now sold out at Net-a-Porter. But not to worry: for those of you who didn’t like the $630 price tag as much as you loved the dress, there is an alternative. The Cooperative Tank Dress at Urban Outfitters nods to the original version with an almost identical color scheme and a similar scoop neck. It is a simpler take on the vibrant stripes, in cotton and sporting a shorter hemline. This dress also goes sans waist-tie—allowing you to belt as desired, and with a $50 price tag, this is a look worth wearing.
