I’d argue it wasn’t forgotten in the prequels. Most of the characters and plot revolves around and is supported by very large well funded organizations (Republic, Trade Federation, ect) which means the clothing and equipment they have is less likely to be worn down. The same can be seen in the original trilogy with the Empire, storm troopers and imperial ships are well polished and not “used”.
