I have so far bought three styles of leggings from VIV Collection and I'm currently hooked!
Pros: They are extremely soft, flattering, and the prints are exactly as pictured. The price, though comparable to many other brands on Amazon (many of which I haven't tried), is way better than you'll find in stores for a comparable product. I have worn them a handful of times and have had no problem with runs, pilling, or holes. I have had no problem washing them on cold and gentle cycle and then hang-drying them. The prints are extremely cute and I always get compliments when I wear them. They are also exactly as pictured.
Cons: They are not warm or fleece-lined, which I expected when I bought them. They are fairly thin (but not at all see through). I live in the south, so I don't need much insulation out of my leggings, but that may be a problem for those of you in colder climates.
