It's a mock neck. It also has pockets, and the color is something you don't often see. Mock necks themselves are rare, so the market price is high, but this one is offered at a slightly lower price. The color in the first and second photos looks different due to the lighting, even after taking many pictures. The color in the second photo is closer to the actual color. It's not as bright as turquoise, but brighter than green. Length: 77cm Width: 55cm Turquoise blue Tiffany blue
