When worn, the waistline's seam creates a slimming effect, making your figure look better. The lining extends below the seam, providing peace of mind. I think you can use it for formal occasions as well. I've worn it about 4-5 times. There's some slight fuzzing, but no noticeable pilling or stains. If you have any other questions about the item or its size, please feel free to comment! Color: Beige系 (Beige-based) Pattern: 無地 (Solid) Season: 秋冬 (Autumn/Winter) Damage/Tears/Smell: None
