Hi guys. I've decided I want some new bedding. My old set has been with me for quite a while, so I'm looking to upgrade to some of Frette's more luxurious offerings. What I had before was nice, but I know a higher thread count will please me even more. Do you guys know if the Frette sets off of Bluefly are up to snuff? Are they being sold for that price because they are somehow blemished or something? Can anyone recommend tips for buying sheets? How many sets is best to get, in the interest of maintaining them for at least 5 years?
