Miu Miu By Prada Spring/Summer 2001, Blue Cotton Button Up Convertible Shirt With Extra Button To Wear Open Asymmetrically. You can wear this as a typical shirt but much more interesting to use the off-set button and wear it as it was shown on the runway, asymmetrically with an open front! There is a seam down the center  back; cotton has a slight sheen to it. It hasn't really been worn though there is a hint of fading in the crease fold of the collar from age though not really noticeable. An important piece of Fashion History from The Well-Loved Miu Miu Men's Line that lasted for only 10 years (1999-2009) and is beloved of Fashion Insiders!
A very unique piece! 

Composition is 100% Cotton. Dry Clean Or Hand Wash Only. It is sized 38/15  (It is a little bigger than it's sizing), Please see Measurements Below! 

I don't remember wearing it often or at all really. There is the slight fading in the collar fold and on the shoulders along where the shirt touched the hanger all these years (hard to capture in a pic). The composition label is blank due to age/laundering. I purchased this at either Barneys NY or at the Miu Miu Boutique in Milan.
