Short is short, but short models should know their proportions
These are shots of my legs. Keep in mind I am super short, prob shorter than you, and one of the shortest models in NYC, if not the shortest. But there are ways to short modeling appear longer, without Photoshop or airbrush, but really KNOWING your body and how to work with it as a shorter girl.



The idea in modeling if you are shorter is not to dwell on what you are not. Ok, so you are not giraffe tall. And heels can only really make you a few inches taller but if you know your body you can look more proportioned, longer in photos, and this CAN indeed help you book modeling work when you are short.
Trying to look a bit taller in modeling is not about "hating that you are short or wanting to be something you are not," instead it is about looking proportioned for the sake of the clients needs and wants. Ideally a client won't tell an agency " I want a 5'3" model, or 5'4" or even 5'5"" ...but if in your photos you can look longer, you could book some work.
