This is a set of two pieces, ivory and green. Both have been worn 5-6 times. They haven't been put in the dryer, so I think there's little deterioration, but because they are a very soft material, there might be some loose threads. (I didn't see any upon a quick inspection.) Because they are a very soft material, they become wrinkled like the photos just from being washed once. They are also highly stretchy. The feel of the fabric is also very nice.
