-I have hair that drops about three inches below shoulder (not too long nor short).
-It is wavy and little frizzy (due coloring for grey hair).
-It is black (or very very dark brown).
-I have a brown complexion.

I feel very comfortable wearing a plaite. But will that look good on a suite or pants.

I have a job interview in an office today. I’m going to be wearing a black business suit, with a white shirt under the jacket. I’m not sure how to wear my hair tho. Normally, I wear it down, but I’m afraid that I look too young. I am 25 yrs old, and have a young looking face (ppl often mistake me for a high schooler). I have long, straight, blond hair. Is it too plain to just pull it back in a simple ponytail? What can I do to help me look more professional? Thanks!

I currently go for a short regular hair cut. But, I want to present a serious and professional image. I should not be distractful at all, but something which adds value (if adding a value is possible at all). Are there any services available which suggest such styles based on our personality?
