Product Insights
The Essential Blue Shirt by Etro is an out-of-stock straight-fit shirt in stretch poplin (97% cotton, 3% spandex) that breathes, resists sagging, and has a lightweight yet opaque drape. It features genuine mother-of-pearl buttons—used since 1770, costing 10× more than plastic, resisting heat, chemicals, and chipping, and verifiable by a gritty feel on teeth—while its tight weave and straight fit further resist sagging, creases, and pulling across the back. The tradeoff lies in care: machine-washable on gentle cycle is possible, but dry cleaning is safer to preserve the button luster. Sizing is by neck circumference in cm (38, 39, 41–44).
