This is more of a fashion tip than a beauty tip, but I'm hoping you'll let it slide. As someone who's a few inches taller than the average woman (fun fact, the average height of an American woman is roughly 5 ft. 4 in.), when I buy a maxi dress there's usually no extra length to accommodate shrinking. And, if you're lazy like me, I'm not going to hand wash my maxis.
In order to make sure you don't end up with a tea length dress, the process is two fold. The first is the most obvious, don't put it in the dryer. Secondly, when you take it out of the washing machine, put it on a hanger and let it air dry (making sure the bottom of the dress isn't touching the ground). I've had dresses that looked like they shrank a good 8 inches but once I hung them and let them dry, they were as good as new. The weight of the water moves towards the bottom of the dress, stretching the fabric back to it's normal length.
