I dont judge anyone who wears juicy at whatever age, but I do think when it comes to the bags, if its not the demure leather ones, that mid twenties should be the cut off. I'm not a fan of the sweat suits on women over that age as well. Thats just my preference, I know some like to travel in them, but even then I would suggest mixing a different hoodie with the pants or vice versa. I mean the slogans are always "girls who...." not "women who..." but thats just my opinion. I don't carry the bags but I bought a bunch of their aztec accessories this summer for inside my hand bag, I do disagree with above posters that its worse to see a young teen with LV than a 50 year old with a juicy velour bag... In that scenario the 50 year old looks like shes trying too hard to look younger, which, where I am from is what people's general opinion would be...whereas the teenager is trying to carry what celebrities of all ages carry or what their mothers or older sisters are carrying..
But when you live by the saying wear what you love, its with the understanding that people may not love it on you.
