This is an interesting question...
For the purposes here I suppose the following definition would be suitable:
"any object or nongenital part of the body that causes a habitual erotic response or fixation."
I suppose for me to boil it down to body parts aside from the face (where all the lovely reactions culminate!), it would be a woman's hips, butt, back and neck...  I don't consider the appreciation for the hips and butt unusual or fetish-like, as they are secondary sex characteristics and evolved partly for the very purpose of stimulation, as near as I can tell...  But a woman's neck?  That's one of the greatest things in the world -- especially if she wears her hair up to show it off, with a few dangling strands...  Absolutely beautiful to me.  Some of my most popular college fantasies (and pasttimes 😉 )involved lightly biting, "playful vampire-like" along a woman's neck...
As for object?  I love certain "types" -- I think this is a common fetish too, though...  Maybe it boils down ultimately to costuming...  Roleplay would be fun -- but I've always loved the appearance of female gymnasts, cheerleaders, figureskaters, and to a somewhat lesser degree, ballerinas (often the thinness puts me off).
