I just purchased my first pair of Rag & Bone/JEAN and I completely understand the obsession. We just got in three new pairs that are to die for!
I'm a fan of most things ombre and this pair of Rag & Bone/JEAN Legging in Rusted Ombre is one that definitely fits the bill. They are super lightweight and soft so they are comfy to wear all day long. Black fades into a rusted color just at the knee.
Anything with leather on it is extremely trendy right now, so The Jekyll jeans will fit right in. Slightly faded denim on the front with soft leather panels on the back. These jeans are cool and laid back, yet have a touch of sophistication because of the leather detail.
I think the RBW 9 Zipper Jean is a nice pair for a night out. They have a darker wash with a slim fit and zipper details on the hips and ankles. I think they can be dressed up nicely with a pair of heels and a silk top.
