Everlane's pitch is "Luxury Essentials for under $100". Their stuff seems pretty well made, but there's nothing particularly luxury about it. Also, their collection is extremely small, comprised of ordinary t-shirts, tote bags, backpacks, a very nice-looking canvas and leather overnight bag, and a thin belt that would probably look better on your girlfriend.
The Frank & Oak catalogue is a lot deeper, comprised of sport shirts, sweaters, polos, cotton trousers, tees, accessories and more. Everything is $50 or under. The shirts and trousers, with their tiny collars and severely tapered legs, are probably best suited for the high school through first job demographic, but the lambswool v-necks and cardigans in nice colours (again, $50) are solid staples for everyone and their grainy denim and chambray pocket squares at $20 are a cheaper alternative to similar but pricier offerings from The Hill-Side.
