Symbolisim

Gwen Stefani doesn't focus on one feature in relation to symbolism, but the thing that the audience likes to notice is the fact her makeup and hair always stay the same.
through the use of makeup and hair gwen us symbolising to be plastic, almost to be barbie, which is a child's toy, this could either be symbolising that gwen has innocence or on the other hand she could be sexualising something that is deemed to be a toy.
in most pictures of gwen you see the red lips and blond hair, this is what most people would deem to be sexy. gwen Stefani as a whole symbolises femininity and sexuality through the use of cosmetics.

A Barbie doll has even been created of gwen Stefan as gwen herself is the perfect barbie symbol.
