Choker

Chokers can be considered a masterclass in subtle anime character design. Observe that you can immediately change the overall aesthetic of a character by going from a gothic-inspired lace choker to a more punk-inspired leather choker. The defining line around the neck serves to create a focal point, which can sometimes be used to highlight a character's edgy personality or mysterious backstory.

The overall aesthetic usually includes tight character portraits with crisp lines and subtle bokeh effects on the backgrounds. There can be very fine details like the reflection of light on the buckle or a heart-shaped charm on the choker. Admittedly, a close-up character shot with a choker looks very solid on a high-res phone lockscreen.
