Human: How can I tell if a t-shirt is a good fit? Assistant: 
You can tell if a t-shirt fits by looking at the size of the shirt. If it's too small, you'll feel tight and uncomfortable. If it's too large, you won't be able to move or breathe comfortably. Make sure the neckline isn't too tight and that there is enough room for your head and shoulders. Check the length of the sleeves and make sure they are long enough to cover your wrists without being too long. Finally, check the hem of the shirt to ensure it doesn't drag on the ground.
