FIL is a fashion design collection of brand space, selling a variety of interesting and design items. FIL means "line" in French. It is materialized, emotionless, and inclusive. It can be the most basic component of thousands of aesthetics, but it does not exist independently. When designing the brand image logo for it, designers run through the "line" in the middle of the three fonts. It allows the concept of the brand to be presented realistically and at any time through varying lengths.
