Wardrobe, Hair and Makeup - Michelle says so
There are people out there who are available and more than willing to help you with your styling - it's their job! You are probably already getting your haircut. The number one tip from my hair stylist was to bring a picture of the look you're going for to your appointment.
You can make an appointment at a department store at a makeup counter for help in selecting a foundation and other skincare products. Women working at the store of your choosing know the fit, style and selection of the merchandise they are selling - ask for help!
Michelle Obama devoted a chapter of her book to sharing her experience in managing the expectations of the public gaze. You can read an excerpt at this link from Elle magazine, but the book is the best selling autobiography off all-time, so you may want to read it all. I enjoyed the audio-book, which the author reads herself.
