If you want to recreate Ashley's look, you'll need a linen sweater (I think hers is Lutz and Patmos) like this one from J Crew, on sale for $39.99. It does differ from hers, but I think it will give you a similar look.
You'll also need some skinny jeans ($39.99 on sale), a double stranded gold necklace ($5.80), and some lace up sandal/booties ($68.80). You can click on any of the photos below to purchase these items. (Click here for a second shoe option for $23.80)
