I accidentally dried one that I didn't want to dry... but there is one I intentionally dried at least a dozen times because it was way too big and it only had limited results.

If it's not pre shrunken. Though I still find them to sometimes depending on brand they shrink minimal0

Some cotton shirts are pre-shrunk. Otherwise you can sometimes avoid shrinking if you just tumble-dry or otherwise dry it on low heat. If you want to make it shrink put it in the dryer wet on high heat.0
