Things I liked:

1) Features a lot of Chinese embroidery and fabric. And not just one region's techniques, but various people groups, styles and eras. A lot of these techniques are thousands of years old. It's a bit of a history lesson, but I love it.
2) Leads. I like the actors and I think they portrayed their roles well. I especially liked how they wrote the FL's character. She's confident but not arrogant, stands her ground but is kind. Lovable, and definitely not annoying.
3) Beautiful framing. From scenery to the runway, I thought the shots and framing were beautiful.
4) Music fit the drama. Although nothing stood out, the music was fitting.

Things I didn't like:
1) Pacing. History and fashion lessons aside, the pacing of the whole drama was slow. Very slow. I felt like watching the drama at 1.5 speed was more fitting. A lot of slow walking down the street or staring off into space shots.
2) I thought the "bad guys" could have had more dimension to them. Perhaps more character development? I don't know, they seemed kind of flat.
