Well if you don't like makeup you might think about some nourishing products for your face and hands...
maybe plant based and organic...
for example jojoba or coconut oil products (unless allergic)...
this could give you a fresh and well tended look, something people notice...
well concerning makeup some lipstick could also make a difference... you might simply give it a try...
you could look up a vid called "Plastic Surgery With MakeUp Fuller, Bigger Lips", its possible to do this with two lipsticks in unobtrusive colours.
A few minutes and its done... I'd also recommend organic, two lipstick and a pencil. I'd rather have a few items of good quality.
And imo part of it all is simply a natural aura... not too stiff, a bit relaxed, nice and easy gait... I'd say try to relax...
and if people misgender, which seems to be rare enough, you might think about taking it with humour...
