You do not need a drawer full of training kit. Two sets are enough for four sessions a week, if they dry overnight (sample guide).
Synthetic knits dry fastest. Wash them at 30 degrees, inside out, and never use fabric softener: it coats the fibres and stops them moving sweat away from your skin.
Hang tops and leggings on a hanger rather than over a radiator. Heat breaks down the stretch fibres, and the leggings that were squat-proof in the fitting room stop being so.
