In the previous post I argued that LoRA per character is often the strongest fit for visual identity. But what happens when you want to render that character wearing a specific item — a shop product, a user-uploaded outfit, a gift from another user? LoRA helps stabilize the character.

IP-Adapter pulls features from a reference image. If both are too strong late in sampling, the face can drift toward the reference. Balance: moderate IP-Adapter weight (lower half of 0–1) with early handoff (IP-Adapter releases control before the final denoising steps).…
