How to make T-shirts longer:<p>Wash as usual and then hang on a plastic hanger until dry.  So, don&#x27;t use a dryer and just let them hang, starting when they are still wet from the washing.<p>Also works when hand wash and rinse but don&#x27;t squeeze out much of the water, that is, hang them while they are still wet enough to drip.<p>Also works with knit polo shirts.
