The Sock Test is a Summer Club ritual: wear the Summer Club Sock during self tan application to create a clean, deliberate tan line — then pull the sock down to reveal it.
why it matters.
The Sock Test is how BGE turned the tan line from a self-tan failure case into a self-tan signature. It guarantees a clean break, gives the application a defined edge, and — culturally — is the moment we post.
Drop 01 of BGE is built around this exact mechanic.
