Building your wardrobe is just as important as building your résumé. Your clothes affect the first impression you give others. It does sound shallow to say that what you wear is judged. What if you can't afford to spend more than $100? What if you actually can, but you're more on the practical side? What if you just do not know how to style yourself?

No worries! That's what I am here for. I have gathered some of the staples and statements that should be in your closet.

Yes, there will a few expensive pieces included. It might be daunting, but the key is to invest in quality clothing that you can mix and match with cheaper pieces!

1. Black suit

Whether you are in the business field or not, a black suit is a closet staple. You can wear it with a classic white dress shirt or mix it up with a patterned top. You can even go for an all black look with a pair of bright-colored shoes. A black suit is very easy to style. If you're feeling a little bit more creative, wear the blazer with a different pair of pants or wear the pants with another jacket.

Blazer, $69.90; Pants, $45.90.

2. Turtleneck sweater
