Sailor uniform, school uniform, navy, short sleeve

This is a short-sleeved sailor uniform in size S. It has a front zipper and fabric buttons on the chest.
⚠️As it was worn several times during the summer, there are yellow stains on both sides as shown in the photos. They are barely noticeable, but there are also some similar stains around the collar. Additionally, a part of the skirt pocket is torn.

This item was purchased at a low price and is not in the best condition, so I am open to price negotiation.
