I ordered the blue in a medium. Fits perfectly for a US medium. Nice long sleeves- I have long arms so I love that!  The button areas are a cream color, not white, so its a nice soft contrast.  The sleeves have a slit where the buttons are- really different and cute.  I wash it in cold and hang dry and it looks new each time.  This is the 4th thing Ive gotten from PattyBoutik and theyve all been wonderful.
