Red Christmas jumper with reindeer, lost in Cardiff city centre

I’m hoping someone picked up my red Christmas jumper after the market yesterday. It’s a medium-sized knitted jumper, bright red with a white reindeer on the chest, and a fuzzy white trim at the cuffs. It’s a bit pilled from wear but still warm and comfy. I was wandering the Christmas market area near The Hayes, around St Mary Street, yesterday around 3pm, and I must have slipped it off somewhere between the stalls and the bus stop by WHSmith. There’s a small snag on the left cuff and a tiny reindeer patch I stitched inside the collar that's easy to spot if you peek inside. It was a gift from my grandmother and has sentimental value; I really need it back.
