What an honor it must be for the model who denim companies consider as to having the perfect 'butt' when it comes to designing jeans. Her name is Natasha Wagner, a 34-year-old model. Could she be the reason why you don't really quite fit into your jeans? Either way, she's apparently got 'all the curves in the right places.'

Jennifer De Clark, the senior director of women's design and merchandising for 7 For All Mankind says:

‘Natasha’s curves are in all the right places.’

‘…And having the perfect proportions is key to a great jean that will fit many different body types. She is the perfect size 28!’

Black Orchid designer Julien Jarmoune also noted that Natasha, who is 5’8″ and slender with a hint of curves, has the ‘perfect marriage of body types’.

With her 28-inch waist she is the median in the standard range of jean sizes, which typically run from a size 24 to size 32.(via)

It turns out, Jen Selter's butt isn't the perfect one after all.

Here's more pictures of Natasha helping out designers.
