Starter Character accessories

Alright, so I’ve recently started development on a medieval Scottish based game where I want the users on the Scottish team to wear a certain piece of attire when they spawn in, I am having trouble fixing it so that the kilt stays on the character and doesn’t fall off and fly away,

Basically I’m asking for help welding an accessory to a starter character, any help would be appreciated

For the accessory you’re planning to weld, is it something off from the Catalog as an Accessory instance, or is it just a regular model?

It is a regular model that I made.
