It used to be so hard to find the perfect plain t-shirt. But recently, every kind of perfect plain t-shirt you could possibly want has become available thanks to a number of new brands specializing in this basic - LNA, Kain, T by Alexander Wang (the best), etc. - and we're all eating it up. This is, therefore, the perfect time to invest in a "statement necklace" (although I hate using that term) such as one of the beautiful pieces below, all from Net-A-Porter, all for which I would kill. Everyone will complement you...
