+sidebar_label: Configuring a complex (cloth) outfit
+---
+
+In some cases the automatic setup is not quite enough to set up a complex outfit.
+Let's look at Lachexia's [Dress Lumi](https://lachexia.booth.pm/items/3763311) as an example.
+
+This tutorial assumes you've already gone through the [simple clothing](../clothing) tutorial,
+and will skip over some of the details covered there.
+
+We start out having dropped the Dress Lumi prefab onto the avatar, and having hidden the parts of the
+original avatar's clothing that conflict with the new outfit (namely, Cloth, and setting `bra_off` on `Underwear`).
+
+![Starting state](initial_state.png)
+
+As you can see, there's a ton of extra objects in this outfit. The automatic setup described in 
+the [simple clothing tutorial](../clothing) will create the Merge Armature component for us, but
+the rest of the objects require a bit more setup. That being said, that's still the right place to
+start:
+
+![Basic setup menu](base_setup.png)
+
+Next up, we need to set up bone proxies to get all those collider objects to move along with their
+base bones. To start, we'll select all the "Hips_Collider" objects and add an `MA Bone Proxy` to all of 
+them at once. Under "Target", drag-and-drop the Hips object from the original avatar.
+
+![Setting up hips colliders](hips_collider.png)
+
+Note that "Attachment Mode" will automatically update to "As child; keep position" when you do this.
+
+Go ahead and do the same for the other bones/colliers as well.
+
+Finally, set up blendshape sync components for Skirt and Tops:
+
+![Blendshape sync setup for Skirt object](blendshape_sync_skirt.png)
+![Blendshape sync setup for Hips object](blendshape_sync_tops.png)
+
+## Other extensions
+
+You could fully automate the setup of this outfit, by adding a Merge Animator component which would
+set up the base Body blendshapes (torso_thin => 100, elbow_off => 0, bra_off => 100), and disable Cloth.
+However, this could interfere with outfit changer configurations, so it's not necessarily recommended.
