There isn't anything wrong with how it looks in my opinion. The issue is that it's probably poorly constructed and made from inferior fabrics. From my experience, JCrew produces a lot of shitty products that won't last for even 6 months without the stitching coming apart or other malfunctions. This is especially true of their knitwear. Save up some money and go buy yourself something a little better, whether that's from Pringle of Scotland, SNS Herring, Loro Piana, etc. is up to you.
