What does SLG stand for Chanel?

Could you please clarify what the acronym "SLG" stands for in the context of Chanel? Is it referring to a specific product line, a marketing strategy, or perhaps a term related to the fashion industry that Chanel uses? It's not immediately clear to me what the abbreviation represents, and I'm curious to know if there's a specific meaning behind it that's relevant to Chanel's brand or operations.
