There are some certain trends that are created for teenagers rather than mature women.
Make sure that you do not own the following items:
1. High-waisted jeans
High-waisted shorts and jeans do not make mature women look any better. This type of pants will only make you look older and more old-fashioned. Consider wearing medium-waisted items.
2. Micro-mini skirts
Micro-mini skirts look trashy even on young girls. Even if you are proud of your legs, get rid of micro-mini skirts if you have any. Replace this stuff with something more appropriate.
