Heathers: Shatnez?

Question:

Hello. I am concerned… I purchased a clothing item (undergarment) that was assumed previously to be completely free of wool. It is all cotton and polyester. That being said, the label says ‘Heathers: 90% Cotton / 10% Polyester’. I looked up what heathers means and it is (maybe) referring to an effect created by combining two or more different colored yarns/fibers. So, initially I was thinking “okay still, this must not be a problem as it says ‘90% cotton (and 10% polyester)’ so therefore the fibers and/or yarn must only be cotton and polyester”, but going further down (in the Wikipedia article) there may be, if I am reading it correctly, a discrepancy in the percent of cotton being labeled, where there are allowances for certain levels (it didn’t specify) to broadly be labeled as even 100% cotton. So this caused me concern! So I looked online and found that the company does not use animal products– but they are also not claiming 100% vegan products. Given what I have previously read, and that these claims are from secondary sources, I am questioning whether I can wear this! Any ideas? Super specific I know, but maybe you can point me in the right direction. If I am able to get in touch with the company and ask about the specific product do you think that is necessary or trustworthy? Thank you, thank you, thank you.
