I purchased a pair of dansko shoes, size 39. I have two pairs of dansko shoes and just love them,both are size 39. So when I saw this gorgeous style of dansko on 6 pm at a reasonable price, I ordered a size 39. 6pm.com arrived within 5 days and turned out to be way too big. I had to pay $15 in shipping fees to return them and was hesitant to order a size down in case 6pm.com didn't fit either.
