I find polyester virtually indestructable. I wash with whatever I am washing as long as colour and texture are similar, though the colour is usually pretty fast, as shown how hard it is to get stains out.

I believe it is the weave type that affects it's wash and wearability. I throw out, most of my polyester garments I throw out as I get tired of them .

Some I have had for many, many years and some I have even remade. Let us know what you do with yours.

Will be interesting.
