LayeredClothing behavior different on NPC vs Character

[Whincify]

I am working on adding LayeredClothing to an in-game catalog, and while the clothing applies correctly to the player’s character, it does not properly wrap on the character inside the viewport. The viewport character is simply created by getting the applied description from the player’s character and applying it to an R15 rig. How do I make it apply the same to both characters? An example of the behavior is provided below:

Applying layered clothing to NPC via client

I am working on making an in-game catalog. Currently, when the player tries on layered clothing, it applies correctly to the player but not the player’s clone in the viewport. I am not sure if this has to do with me applying it via the client or if there is something else I am doing wrong. Video of current behavior: https://gyazo.com/746e588a4a4fa9373635a1a0acbf105b
