This shirt is cute. It's not a particularly novel fashion choice, and definitely a wearable declaration to say: "I have somewhat of an understanding of design". It's worn with at least some intention to earn street cred amongst the fashion-y crowd. But not entirely. If you're a huge fan of Rei Kawakubo, and find her main line to be a little "aspirationally" priced, this is a way to support her design philosophy without breaking the bank.
The shirts are comfortable, accessible, and don't require any particular cleaning care. It's find just tossed into the washer and dryer. The price is a little steep for what it is, but given the prevalence of Play in pop culture recently, you don't need to pay MSRP anymore. It's not hard to find discounted versions of the shirt offered by third party vendors.
The Play line is very wearable, and this shirt is no exception.
