I don't know, maybe Victoria is hiding a lingerie fetish, or maybe Victoria saw way too many weird stuff and wanted to encourage others to keep their underwear a secret... who knows... ╮( ̄▽ ̄)╭ reply
According to wiki: "The store was named in reference to Queen Victoria and the associated refinement of the Victorian era, while the "secret" was hidden underneath the clothes."
The lingerie she's wearing below her outfit is the secret lol reply
