She is wearing: Ralph Lauren Black Label cashmere sweater, Vince denim jeans, Espadrillesetc.com flats (here).
I instantly knew I wanted to recreate a budget-friendly version for myself. I have omitted the captain's hat, so the look doesn't come off as "costumey" and I chose these fun lobster print espadrilles, instead of a solid navy color (though the pair she's wearing above are affordable, too). My picks:
Merona Navy Boatneck Sweater - $24.99
Etienne Aigner Urban Print Espadrille Flat - $29.95
Chaps Nautical Red Denim Capris- $38.50
