It’s to my understanding that Roblox is completely against the utilization of classic clothes with newly made modern bundles, but despite that, I’m still seeing new ones being published every so often.

I’m unsure if it’s due to my inexperience as a new UGC creator, but I’ve been unable to find any proper resources that provide any in-depth information. I do not mean utilizing any free body bases, but a full guide on how to properly create, import, and publish a bundle that supports 2D clothing from scratch. I have my own bundle fully finished, it works completely fine in studio, and is fully validated. It works with any 2D shirt or pants that I apply onto it in studio, but when published, 2D clothes that I have equipped are not applied to any limbs equipped from the bundle. I assume this is because of my confusion on modesty layers
Regarding my confusion on modesty layers, I’ve seen a fair deal of bundles without anything covering the required regions, but still work the same as all. Again, my confusion mainly stems from the lack of documentation on Roblox’s side for classic clothing, so It would help very much if a proper explanation were given when it comes to modesty layers and new bundles that support 2D clothing.
If there are any who are well informed on the topic it’d be a great deal of help if most of these things were explained a bit more.
