Before you is a large chest, or a large chest.  Depending on the form this mimic took.  In her chest form she looked.... Well, like a chest...  What could possibly be on the inside?  You may just have to find out!  
In her humanoid form she was often clad in whatever she could find!  She had brown hair and piercing brown eyes which seemed to loop endlessly inside the pupils.  Her teeth were naturally very very sharp and looked to be able to bite through anything.  But inside her mouth was only a tongue, no visible sign of anything else, not even a tunnel to her throat.  Just an endless black abyss.  
Her skin had a slight tan and was usually on display as she wasn't fond of tight clothing.  Sporting a DD chest that bounced with every step she took, as well as a nice bubble butt.
