The look of your brows can change according to your makeup style. For example, when I want to create smoky eyes and light lips I usually make my brows appear defined but definitely soft, whereas when I want dark lips and light eyes I prefer a slightly darker brow. This is based on preference, so you should make your own choices depending on what type of look you prefer.
Lovely shaped eyebrows act as a frame to set off your eyes, just like how your hairstyle sets off your face and a picture frame sets off a beautiful painting. It's certainly not an exaggeration to say that brow shape can make - or break - your look. Now you can lovely brows too!
