Restricting apparel by body type

[Kyna Tiona]

I've encountered an alien race mod that also adds utterly adorable clothes. By default, the mod restricts the clothes to being only wearable by the mod's race, meaning it only has textures for the race's body type (thin). I'm trying to figure out a way to restrict the clothes to being only wearable by the same body type instead, that way I don't have characters equipping clothes that immediately become invisible.

Is it possible to do this through adding settings to the def files, or would doing the above be a very involved effort?
