Yes, you can wear teal shadow without looking garish -- just follow these steps
This tutorial is designed to show you step-by-step how to wear bright colored eyeshadow (which is doable even if you have small or Asian eyes). Brightly colored eyes can dress up a look when paired with a neutral or nude face, or accessorize an entire outfit. Just make sure you know how to wear it before rocking it in the office.
For my part, I think that Asians and women with deeper skintones wear bright eyeshadows better than their lighter complexioned sisters.
