People make tattoo on their body with various subjects like human faces, names, words, symbols etc. This kind of tattoo may be temporary or permanent but it is hard to see somebody who painted a trouser on her body and roaming in open public places. The model in the picture looks fully dressed up from top to bottom even though her skinny jeans is fake, painted on her body. With a gold backpack the blonde model is very unlikely to identify her original dresses. In the picture this lady looks pretty confident on her belongings.
