DGAGA Little Girls Cute Cotton Floral Nightgown Sleepwear Pajamas Sleep Dresses (9-10 Years /150cm, pink 1)

This came with no size I ordered a 9-10 for my granddaughter for Xmas so I don’t know if will fit ? Is it a 9-10 I just don’t know , also it’s line dry what young family is going to take such care ? It’s very thin . That’s why I’m only giving it a 2 star not know if is a 9-10 is very discouraging !!!
