Have you heard about Everlane?
I found it via Cup of Jo. It's a company selling designer-quality tees at realistic prices (they advertise via word-of-mouth and only sell direct-to-consumer online, keeping prices down). A well-fitting tee for $15? Yes please. I'm not a big wearer of t-shirts, but my curiosity was piqued.
A visit to the website requires a log-in/membership (free, requiring only basic information). Once in the site, I found really nice tees for men and women, attractive unisex belts (my big girl insisted we have the red one) as well as totes, weekend bags and backpacks in simple, classic styles. Everything is less than $100. Shipping and returns are free for the first 24 hours of your membership, just to get you hooked (can you resist?); after that time, shipping is free when you buy 2 items or more (pretty easily done).
As extra incentive, if you pass the info along to friends, their visits open your access to the Secret Shop. You want to know what's in there, don't you?
