Maximizing All Your Stats At Once
There doesn't seem to be a convenient way (Mafia, the wiki, whatever) to figure out items that maximize all your stats at once. So, here is a partial list. Afterwards there is a list of disclaimers. Some things were omitted on purpose. Some things have stat requirements, and/or are expensive. Others are not tradeable, or not conveniently tradeable. Look before buying if you don't have something already. In general, the assumption is that you are in aftercore.
These figures assume you have all of the outfit pieces. May or may not be the best or most cost-efficient option, depending on your base stats and what you can equip.
Flaskfull of Hollow is pretty much always worth using if you reach a point where you need more stats and gear is not enough. Other items which give Smithsness may be worth considering, particularly if you do not meet the stat requirements for better gear.

Custom items and rare (or rare-ish) things like rainbow pearl jewelry and radio prizes are not on this list. Ditto items that came from convention promos (unless there are few or no other options in that slot), or stuff that is old/expensive/unobtainable now and has newer and cheaper replacements. Also I didn't bother with +1 and other low-bonus gear when better options were available. If your stats are very low you may wish to consult the Dressing For Success pages for individual stats to see other options. The general assumption is that you are in aftercore.
If I left something else out that isn't covered by the above disclaimers, feel free to poke me in game.
