I purchased this from SHEIN last month. My daughter wore it once, but the waist was too tight, so I'm putting it up for sale. The inside is fluffy, so I think it will be warm. However, it's not as fluffy as Uniqlo. Currently, she's between sizes, wearing a Uniqlo skirt size 140 or 150. So, if you've just started using Uniqlo size 140, I think she'll be able to wear this a lot. Inseam: Approximately 61cm Rise: Approximately 24cm Hem width: Approximately 23.5cm I plan to ship on weekdays.
