I believe the issue was this but it no longer shows up on JIRA:
Request for Rigged Mesh Parametric Deformer
This is a request for a parametric deformation feature for rigged mesh items. In producing rigged items such as full avatars, partial body parts or clothing items, once an item is uploaded and worn there is currently no way to adjust the item for the many variations in a persons existing shape. The ability to personalize an avatar is one of the primary psychological keys to creating a virtual identity. Currently rigged mesh items do not allow for viable customization, limiting both usability and marketability for what is clearly the largest economic market in SL. If a pair of pants or a jacket (made of mesh) are worn, they do not conform to any avatar shape, changing even from the shape defined by using the default mesh avatar object to create them; when uploaded and worn, they do not retain the original shape as they should, but are considerably scaled, making it extremely difficult to match to even one existing shape, let alone the many variations possible.
A rigged mesh parametric deformer is essentially a cagee-type system which automatically adjusts an item, scaling it to a predefined boundary outside of the existing avatar mesh polygons, regardless of the items polygonal shape, layout or UV map. In practical application, it appears to "shrink-wrap" your item to conform to an avatar. It also provides and opportunity to implement a layering system so that, for example, an item placed in a lower layer would appear slightly under (and remain under) and item placed in a higher layer. This hierarchy allows for a shirt to go over a pair of pants, and prevents the pants from showing through the shirt item, while both items still conform to the existing avatar mesh shape.
Additionally, this type of parametric deformer layering system would allow a resident to wear an avatar shape, and then wear items or clothing from another provider on that mesh avatar, yet again extending the capabilities of all rigged mesh items by allowing them to be used together regardless of your original shape and where your acquired those items; they would still work together effectively.
This problem is identical to the mesh item attachment issues encountered in early versions of the BlueMars virtual platform, which were very effectively resolved with the introduction of a layered deformer system as mentioned above. The introduction of that system eliminated the scaling/sizing problem and eliminated the need for rigging, thus opening up the platform for a creators to market a wide variety of items that could be used together with no limitations to existing size and shape of the avatars.
This request is similar in some ways to https://jira.secondlife.com/browse/CTS-452 , yet different in many ways.
And the added suggestion from DanielRavenNest above.
