Remember that there is no standardized sizing, so don’t be alarmed if you’re two sizes bigger than you think you are or two sizes smaller than you think you are. It doesn’t matter. When trying on some pants, you should get help, because it’s really hard to check the fit from behind by yourself.
If you want to look taller, your pants, shoes, and socks should all be the same color, as that will help you grow up in stature.
Wear dresses that have a dark side panel; this will give the body an elongated look.
Solid blocks of color tend to work best.
Be aware that what may have suited you 10 years may cause you to look washed out now, as your skin ages. Always update.
