I hate heather grey. It just might be the worst color there is. I don't understand why people wear heather grey clothes when they don't have to. Once in a while I can make an exception for a t-shirt or sweatshirt, like if it has a school logo on it (as if you're at team practice!), but anything beyond that is beyond me.
Heather grey has several associations I can't suppress. It reminds me of a high school gym class. The kind in 80's movies where they suit you in heather grey duds, presumably the cheapest cloth available, where appearance is not an issue. Why would you wear a blouse made out of gym clothing material? Related: I expect to see sweat stains on anything made of that stuff. And heather grey tube socks I won't touch even if they're clean.
What gives it that cheap look? I can only assume that the manufacturer doesn't bother to fully mix the solid grey and the solid white. It looks like it's made of random leftover shreds of cotton half-assedly blended together and then somehow melded into a fabric. Heather grey is the sartorial equivalent of chipboard.
Heather grey accent stripes elicit this response: Oh, they almost had enough normal material to make a full shirt. All but those thin stripes. So close!
