How to Make a Large Framed Body Look Thinner

Good question, but tough to answer without examining you.  For instance, camouflaging this can be done in some ways through breast augmentation, and sometimes body sculpting with liposuction..  But you are right, you can not change the underlying bony architecture.

One of the key elements of plastic surgery is getting a patient to accept certain features of her anatomy. While plastic surgery can sometime create dramatic changes, this does not mean one should ignore individual anatomical structure. If you have little loose skin and fat, chances are there is very little you can do outside of perceptual changes. For example, even if it is your abdomen you dislike, it might be possible to do something to your breasts instead to make your torso look less wide. It is akin to creating an optical illusion, But you need to consult very carefully with an experienced plastic surgeon.
