Ideally close up the cleavage if the date is in a public area due to scars and maybe him having a problem with it, i think he will carry the conversation and it's cuckery if he doesn't.
Ideally what u can do is calorie deficit, and water, potassium overload but the problem is that it's tomorrow, u seem bloated (could be poor fat distribution) in the first picture as it's better candid wise for the evaluation, i think if u do your makeup like the second picture and blend your nose better i can see a +1 to that.
There isn't much you can do really in a day, cold shower could subside some bloating, ideally makeup and foundation like in the second picture, don't overdress and keep cleavage of any sorts to a minimum, don't do what you did with your eyeliner in the first picture you look like you were crying, lipstick would help make your top lip look less skinny and more pronounced. The problem idk if u can fix since i don't do make up is your bottom lashes, they seem to be everywhere if i'm being honest, so if there is a fix to make them more straight ideally that's it.
