A well-fitting suit not only makes the wearer look energetic and upright, but also enhances self-confidence and professionalism. Studies show that people often have a first impression of "people wearing well-fitting suits" as "more reliable and more leadership".
If the measurement is inaccurate, not only will the suit be uncomfortable to wear, feel cramped or have slipping shoulders, but it will also cause problems such as jacket pleating, loose sleeves, and buttons not being able to button, seriously damaging the overall appearance.
In addition, custom suits are expensive. If the size data is wrong, it is likely to cause fabric waste or require secondary repairs, wasting time and money.

Unlike watercolor, acrylic paint is a synthetic water-based paint that forms a plastic-like film when it dries. This film can adhere to canvas, wood, metal, and even clothing fibers. Once dry, it is almost insoluble in water and difficult to shake even when washed.
Its "polymer solution" determines its extremely high washability and tensile resistance. Once cured, it seals the surface of the fabric like glue.
This also explains why "acrylic paint stains" can survive multiple cycles of washing in the washing machine. Some stains even become "hard lumps" and become more and more difficult to remove over time.
