Which should you buy?
Both $198, so this is purely about appetite for flash. Buy the 7FAM Slimmy if you want a proven slim-straight that fits predictably and offers lots of wash choices for everyday rotation. Buy the Diesel D-Fining if you want a tapered leg and bold, treated denim and don't mind that sizing varies by style. One caution on the Diesel: heavily distressed washes can show wear at the distressing, so skip those if longevity matters more than the look.
