What the Messenger of Allah (ﷺ) said about lower garment also applies to shirt.
Sunan Abi Dawud Book 34, Hadith 76
← Previous Hadith The Prophet (ﷺ) said: Hanging down is in lower garment, shirt and turban. If anyone trails any of them conceitedly, Allah will not look at him on the Day of Resurrection.

Sunan Abi Dawud Book 34, Hadith 75 Next Hadith → Why do you put on the lower garment in this way? He replied: It is how I saw the Messenger of Allah (ﷺ) do it.
