FSA (front separate all-in-one) is becoming a staple for homeless tailors.
The front is separate, so you can wear it like a set. The back is connected, so you can take off the top and wear it around your waist like a jumpsuit. There are cords at the waist and hem. This time, it is made of cotton/wool material because it is the autumn/winter season. The no-collar design makes it easy to layer and wrap around a scarf or other items.
The fabric will shrink slightly when washed, but the unique unevenness will emerge, giving it a nice look. (The product is unwashed when delivered.)
