yes. for instance, if you are a saleperson, with a better look you can make your customers remember you better and keep comming back since people like to see something that look goods. in the same manner, our boss (both your sex or opposite sex) will remember or pay attention to you more than the other ugly or normal looking employees. good looking just help you to stand out of the crowd. it may not an advantage in some particular jobs, but generally, nowadays more jobs require face to face contact than those which dont. so looking good is still an advantage in most situations
