Otfits... cosmetic only?

Do outfits convey any bonuses?

No bonuses. One is necessary to unlock a biome, works like a one-time key.

Basically yes. There's the one already mentioned that unlocks a door in a paid DLC (but you can pick it up in the level, you don't actually need to unlock the outfit and change at the tailor). And another changes some cutscenes in the very endgame, but you also pick it up during a run in a very specific circumstance and get it unlocked automatically. The last update added an outfit blueprint that will only drop if you wear another very specific outfit.

So not all outfits are purely cosmetic, but you never have to worry about unlocking them if you don't care about cosmetics. Their original purpose was giving long-time players a way to dump their otherwise useless cells (because everything else is already unlocked). And that's exactly how I would approach them. Spend cells on useful upgrades and if nothing is left, dump them into outfits.

A warning: you can actually refuse to wear the key outfit, rendering you unable to unlock the other DLC zone. I didn't know how it worked so I did just that on my first foray into the shrines.
