We love a sleeveless tank or gauzy sundress as much as the next person -- BUT going out without an extra layer can leave you vulnerable to over-air-conditioned spaces and evening breezes. The solution? This stretch denim jacket! Its structured-just-enough peplum silhouette balances the airy fabrics and romantic prints you'll no doubt layer underneath, and it feels so much more fashionable than last year's sweatshirt.
