NWOT Ribbed gilly hicks top

Wish I could explain this material but it’s really nice- it’s kind of plush and squishy, really comfy. Got this from Hollister/ Gilly Hicks but forgot I already had almost an identical shirt. Size is large but it’s a fitted/crop style. I am actually a size small and sized up so it would fit more like a Normal top. I’ll list it as medium since that’s right in the middle. Similar style to what you’d expect from aerie I never wore this, only washed it once
