Brilliant thxLoose white clothing is the best thing for long term wear. Soft polyester cotton blends are good, nothing course or scratchy.
Over time a TPE girl will leech out oils on to the cloths she wears, this is normal and will wash out of the clothes.

As I've mentioned many times soaking clothes in cold water with a cup of white vinegar added will set dyes. Avoid cheap Asian made clothes though.
Tamsin has black clothes that she's worn for long periods with no staining.
Also prints don't stain. Printed dresses and tops etc. They use natural dyes plus it's on the outside only.
I usually leave them in to soak for about an hour. Then rinse out and hang to dry.
Tamsin has been with me for three years and has never had a clothing stain.
She had a stain on her bum soon after she arrived from sitting on a chenille armchair but has never been stained by clothes.
