Yellow Brown White Stripe Anxiety (brand) Shirt

I can update with measurements if needed. Says medium but fits more like a S or XS. This might be a Juniors. This is a more fitted shirt that runs smaller. The "undershirts" are fake as you can see from picture. Gently used condition. No obvious stains or holes but im human and its possible for me to miss something. All of my items are from a smoke free home.
