When buying ugg boots from Ebay should you buy a size smaller than your actual size?

I suggest you go to an ugg retailer like nordstro, bloomingdales, tilly's, journeys, saks fifth avenue etc. (wherever they sell uggs) and just go in store to try them on. that way you know exactly what size you are. then you can go home and get the cheaper ones off ebay. be careful though because a lot of them sell counterfeit uggs. you could probably find the cheapest bailey on online on ebay, amazon, or zappos. again be careful with counterfeit ones. if you want something similar to the bailey on uggs, I went to sam's club a few weeks ago and they were selling boots that looked exactly like the bailey ons without the ugg sticker. i got myself a pair and they are super comfy and look exactly like uggs without the label. also try costco for similar boots. i hope you find your uggs. good luck!
