As a general rule, I wear whatever whenever. However, August usually our hot month (not this year, though!), so I mostly wear lighter one-and-done shadows and no eyeliner till the fall weather returns. Because my eye makeup won’t be subjected to heat and sweat, I go back to more intense colors and dramatic looks, with eyeshadow and eyeliners.
Lip colors are all over the place for me, but I probably go vampy more often in fall.
I think blushes see the biggest change for me. I find myself wearing less coral, pink, and lavender blushes and getting more into my plum, berry, purple, and wine shades.
