Green Flannel Shirt

Alright lads and lasses, I had the opportunity to try on this shirt the other day. Cool shirt, nice cut, assemblage patches, wool, smoked mother of pearl buttons, made in Italy, yadda yadda yadda, but $3810?

I'm no stranger to designer, ERD, but like damn. Me and the stylist were both scratching our heads trying to figure out why this is priced higher than the ERD x Loro Piana cashmere sweaters and stuff, almost at outerwear pricing. What am I missing?
