Customer Reviews
Good yoga set, mixed experience
I bought a seamless leggings and athletic crop top workout set. The quality was surprisingly good for the price; the fabric felt durable and compressive enough for my yoga sessions. Sizing ran true, which was a relief. Had a question about tracking, and customer service responded in about 2 days, which was fine but not super quick. Overall, I'd probably order activewear again, just expect a small wait.
Decent bikini, slow shipping
I ordered a high waisted bikini set. It took 10 days to get here in California, which felt a bit long. The material was okay for the price, not luxurious but held up after a wash. I liked the fit.

hey, anyone order from Siysiy before? wondering if their sizing is generally true to size or if I should size up for a bikini top.
