How to style it

One note per detail, from our short style library.

Off the shoulder
Bare collarbones need little: studs or small hoops, hair sleek.
Long sleeves
Bracelets disappear under sleeves, so put the shine in your earrings.
Ruffles
Ruffles add volume: sleek hair and simple shoes balance them.
