There's a reason I take all my outfit pics as a selfie in the mirror... I can adjust my body and my angles and make myself look my best... it's what most people will do, tbh... but people need to understand that the same body can look very different within an instant, and you shouldn't judge someone based on pics. They didn't suddenly gain or lose weight. They aren't pregnant, etc... well, they might be... but they also might be showing a different side of them... literally.
This chic is showing that with the perfect insta-pics. Sometimes using clothing, sometimes using an app to edit it, sometimes using a good pose.
