If the partner you select is the same gender as your doll, they can wear anything in your current wardrobe. That awesome dress you own? They can wear it! Those killer heels? Strap them on!
The cooldown time before you can wear those items again will be shared between both of you. You can not wear the same piece of clothing as your partner in one submission.
If you select a partner of the opposite gender, they will be able to access your owned items for that gender. Imagine how many combinations of looks you’ll be able to create!
