I purchased a wool jacket, a dress, a scarf and a pair of earrings from sheinside. I'm very happy with all of them. Shipping did take a long time, about 3 weeks from the time I ordered, but considering it was travelling half-way across the planet, to me this is understandable.
The clothing fit as described. Make sure you read the measurements on the site and compare to your own actual measurements (no cheating!). Chinese sizes are waaaayyyy different (smaller!) compared to US sizes.
Quality was great!
There were additional taxes due upon delivery, but I think this has to do with each Country's taxation policy, and not Sheinside.
I will definitely purchase from this seller again.
