Then there's some fantastic Yohji Yamamoto pieces at the new online mecca, Hervia Bazaar (which I'm sure I'll talk more about - it just opened yesterday!). With these, you can get the clean front, unexpected details (i.e. double layered front on the black, detachable collar and hanging button length on the white), AND a drapey back. Sigh.
And then, bringing us to the next site of concentrated fashion worship, I heart these pieces by Milan-based dMajuscule. Is that alright?
