using the alternative outfit models?

For both male and female genders, this repo contains 4 personas with models, animations and textures.

It also contains, for both genders, a subfolder called 'alt_outfits' with hoodie/polo/tshirt models and textures.

How do we use those though? if i open the cristina model, it contains clothing and head etc but if i open the alternative hoodie model, it just contain the clothing. What are we supposed to merge both to dress her with that alternative outfit?



Thanks in advance.
