Definitely Grey. Like you know you are already too Hot🔥. 👀You in Leggings is just chef's kiss 😘🤌! OMG lol. Like you said Grey is cozy, subtle really; but your Voluptuous Curvy body makes anything look good. Grey wins in my opinion. The 2nd pair was Fire🔥; too sexy for the Gym. Twerk in that pair. Wear the grey leggings with a Black Hoodie and you are good. Certified Gym Baddie right there. Are you the Baddest Bish in your gym?
