If you have pale skin, try blue-based reds. If you have olive or dark skin, orange-based reds usually look best. A satiny, medium-tone red suits all skin. But there are absolutely no rules. Just get out and try some on!
Tip: Get a modern look by pairing red lips with minimal eye makeup. This avoids looking too retro or heavy and works especially well with a nude eye framed with a defined brow.
