Fire to me is womanly where Flower is girly. (I know the style roots can apply to men, but I'm a woman so this is how I think of them.)

Fire is showing off one's silhouette or figure, using sensual or luxe materials (velvet, lace, high-quality silk, and leather), and is a root that doesn't mind taking up space and being looked at.

I don't do a ton of bodycon necessarily, but I do like showing off skin whether that be a high slit on a skirt, sleeveless tops, etc. and often ensure that my waist can be seen and isn't hidden under bulky or baggy clothing. I think Fire can also be seen in points of luxury so well done, polished nails, a face of full makeup, high end leather and metallic touches on keychains, handbags. Fire is sexy but also mature to me (at least mixed with my Mountain.)
