Please can anyone tell me where to find a fitted long -sleeved tunic top to layer under knitwear this winter. I'm looking for something jersey cotton with lycra or similar. Basically something long but very fitted so it doesn't add any bulk. Ideally grey, ideally scoop neck, not that I'm picky! I used to have something just like this from Zara, I think it was actually a body con dress, and it's just perfect but completely worn out. I'm on a tight budget so nothing too pricey. Thanks.
