The lime green Marc Jacobs retails for $9 and the American Apparel one in blue goes for $16. Personally, I'd go for the American Apparel one. You know me, I'm not much of a risk-taker when it comes to fashion.
The subscription-let's pretend I'm a fashion doctor-would be a well-worn in white button down, easily tucked in dark grey slim trousers (corduroy?), the American Apparel suspenders and cool loafers.
Easy, cool and careless.
