Nicole Rivelli Related: Lily sees beauty where other people don't. How she designs her store and how she imagines her floral designs are the same things we wanted to bring into how she dresses. But I also wanted her to feel a bit masc, in a way.

It was important that Lily doesn't feel like a fading flower or too delicate or that we lean into this ultra femme woman that's designing flowers, and then ends up being abused and kind of make her feel very strong and independent and kind of self-possessed. And I think going into this masculine-inspired workwear, was part of that. Lily has a few pieces that bring in the masculine side, like the Bode patchwork.
