The tailor can make the body of the shirt fit better by reducing amount of fabric.They can also reduce the length to enable wearing untucked. They can also replace buttons. They can reduce the diameter of the sleeves and shorten the length of the sleeve too. They cannot make a new collar, however. He also cannot make a French cuff. Keep in mind that the more changes, the more the cost.  In summary, a tailor can do anything to a shirt to make it fit better.
