Size 9. I bought it at the store, so it's authentic! I usually wear a larger size, and it's hard to find cute colors, so I tend to buy UGGs whenever I find a size 9 in the women's section. I'm selling some of them to organize my collection. If they don't sell, I'll wear them myself this year. Are you looking for a larger size? Classic Ultra Mini Pink 26cm Women's Large Size Color: Pink
