I purchased a set of three at the Aoyama store for about 100,000 yen. These are basic PRADA items, and everyone wants at least one. The color is navy. They feature an elegant sheen and the best feel against the skin thanks to the high-quality cotton. The triangle at the back neck is an accent, making this a highly recommended item even worn alone. They have been used to a certain extent, so there is a feeling of wear. I have decided to get rid of them as part of a decluttering effort.
