Rachel Zoe brown fitted sweater

Beautiful brown stitch sweater from Rachel Zoe. Size S. Fitted. Wide crew neck. Only worn once or twice, perfect condition. Selling because it’s a little bit tight in my upper arms/shoulders otherwise I would wear it a lot :( Not sure how to describe it but has vertical holey stitching details (pointelle?) along the arms and back; 4 vertical lines on the arms and lines across the back that you can see a tiny bit of skin through (not much).
