Where is the armature?? your pictures suggest there is armature but the model is already posed as in picture, and there is no armature in either fbx or blend file or anywhere. You also wrote it's rigged under 3D features on the right. that is called false advertising! So we can't reset your pose and change pose or adjust to our own characters properly. also another bad thing is whole mesh is in one part. you said "mannequin body included for fitting display" but the low poly body is actually merged with the mesh and there are no separate parts. the body and all outfit parts are just one single mesh that is not possible to separate clearly. this is just a figurine not usable outfit! for you should have split the pants, jacket, shows, top etc... that is normal way to do things. kind of disappointed I paid for this I hope you make updates and upload better file. can you send me a file with the rig? otherwise I will ask for refund cuz this is not what it looks like on the page
