I bought this around 2020 and it’s been in a non-smoking storage ever since. Now unavailable from the Smart Doll site, here’s what it says: 
Designed for relaxed days at home, this set includes a soft off-shoulder sweater and a pair of cozy room socks—ideal for when your girls are lounging around. To wear the sweater off the shoulder, just roll down the wide collar slightly.

The sweater, however, is versatile enough for outdoor wear—pair it with jeans for an easygoing, stylish look.
Note that the socks are intended for indoor use only and are not suitable to wear with shoes.

Made in Kyushu, Japan.

No returns, please don’t buy if you have any doubts. Thank you! I’m happy to answer all questions, check out my other actions for more Smart doll goodies.
