Cloudy Glasses + Torn Notebook is considered of the better combinations in this fight since they both increase invisibility. I think Torn Notebook is actually what I used to beat her. I don't remember what I used for armor.

There's also the abandoned quiche, and I believe it's still accessible at this point.

Dog Residue can be pretty helpful if you got nothing else that's good, or you don't want to waste your good items yet.

Toriel's pie is almost necessary. Not for this fight, save it for the final fight.
