[Some practical details]: The button closure helps you put on and take off it quickly; the loose version makes you feel comfortable at all times without losing a sense of style; Pockets on both sides allow you to carry your wallet, mobile phone, keys and other personal items with you.

[How it was designed]: When you first look at the dragon costume, you'll be drawn to the cute and fun hooded hat design. The hood's facial expressions are carefully stitched with electric embroidery, and the cute eyes, nose and smile expression make the whole design come to life; the wearable claw cuffs allow you to wear the claws or take off it to show your hands; and the back has wings and a long tail to help dragon fans complete their role play.

[Composition of the fabric]: 100% polar fleece fabric, washable. The polar fleece fabric is fluffy and dense to keep you warm in the cold winter; the texture is clear and very soft to the touch, and there is no discomfort even if it directly touches the skin; it has a certain elasticity and is not easily deformed, which perfectly solves the conundrum where fashion and comfort cannot be achieved at the same time.
