"Silk sweatshirt" seems borderline oxymoronic--but it's brilliantly wearable. I love it in grey too.

1. J.Crew silk sweatshirt,
2. Bauble Bar crystal earrings,
3. Alice & Olivia zebra bag,
4. Alexandre Birman sandals*, or
5. McQ Alexander McQueen skirt,

*I was recently gifted these high heels, and I adore them!
