Instant purchase is OK. This is a non-sale item that is currently unavailable on the official website. It's a very popular black, long-sleeved sailor collar set-up from LIZLISA. I bought it three years ago. I've worn it a few times, so I think there's some wear and tear. The top of the set-up has the zipper sewn at the top. The pants are also sewn. You can remove the thread yourself.
