You've lusted after the PS1. You've dreamt about the Alexa. But, let's face it, so has everybody else. We know you want to get in on the next It Bag before the rest of Hollywood, Manhattan, and everywhere in between. So, here's a tip--we think new handbag line 1 Per Diem has the X-factor. Take a step back into the New York of yesteryear with designer Vanessa Espinosa, who's crafted a 3-piece collection inspired by 19th century train cases. After working at Commes des Garçons and Issey Miyake, Espinosa decided to set out on her own and apply her expertise to create clutches and carryalls that are both refined and exotic. The purposely pared down line first debuted during Fashion's Night Out at Brooklyn boutique Thistle & Clover and is now also available on the brand's website, which launched on the first of October. These babies are NYC born and bred, all manufactured right here in the Big A--the three styles are named for the cobblestone streets that influenced Espinosa: the Crosby, ($1,180), the Mercer ($785), and the Bowery ($635). They're all made with antique hardware and available in black goatskin, lizard skin, and black pebbled lambskin, meaning you can choose to go dressy or more everyday. If those don't fit your fancy, the Mercer and the Bowery are also customizable in an array of Ostrich and Python skins (prices vary). We know they don't come cheap, but trust us, they're investment pieces, not a passing fad, that will incite bag-envy, well, forever.
