Workout clothes stink. Literally. It helps to know how to clean them properly, but it's also a good idea to assign one or two colours from your wardrobe exclusively for gym wear and nothing else. You'll always know which clothes to keep separate.

As Jezebel explains in its reeky gym clothes guide, that funky smell can persist even after a wash. It could be due to the material, such as spandex or lycra. It could also happen because the water can't penetrate the fabric due to a build-up of body oil, detergent or fabric softener in the clothes over a long period of usage. Whatever the reason, you don't want to accidentally wear a shirt and go out, only to realise that you're stinking.
Our simple solution is to choose a couple of colours that are exclusively meant for workout clothes. Shirts, socks, towels, underwear -- stick with one or two colours and you instantly know what to wear to the gym and what to wear anywhere else, without risking an attack on anyone's olfactory senses.
The colour choice is up to you, but it makes sense to go for something that isn't one of your favourites -- save that for places where your appearance matters. You probably want to avoid white as one of those colours though, so you can save yourself a separate wash cycle.
