Yes a little makeup goes a long way. With heavier brows, eyeshadows really don't show well I've found, so I started using bright colored eyeliners applied slightly thick.

I don't have luck with mascara mostly because my lashes are thin and too many lay against the skin and with such a heavy brow, I can't get a lash curler in there without pinching a lot of skin.

Also lips. I have thin, blue tinted lips. So a little lip stain of a berry tint goes a long way.

Also avoid dresses or long tops that are solid colored and body contouring. They are great for showing off curves, but also show off the lack thereof. Though adding a thick belt to break up the solid color can fix that some.

A simple bracelet when wearing short sleeves is feminizing, rings as well, just be careful of the finger used since some cultures a sign meaning to that. And a necklace to fill the space between the neck and a shirt neckline, especially if it's lower cut, can help feminize and deemphasize wider necks.

Body shaping wear that's meant to smooth out women's natural belly shapes helps to add some curves as well, though sizing down is likely needed and it only really works well for thinner body types. And of course isn't very comfortable for anyone who wears them and may make sitting difficult or impossible, so I only rarely use that tactic.
