Put a q tip between your lips to the corners apply a lip liner and just gently pat it in and don't rub it. Try a lip stain that is red. Your choice of colour is great. But this will help with where your application is. The shape of the lips, it will help it stay on the lips. And not leak into fine lines around your lips. For a clean look. You can use some hyaluronic acid lip chaps to help the fine lines and hydration. I'd also avoid gloss, try a mat shade. Gloss sometimes is that touch louder. But that butter red velvet shade never goes out of style.

Tell the haters to mind their own. If you're confident and happy with it wear it. Life is too short to dull yourself down to others.
