More suggestions:
Crop top.
A short sleeveless top that just covers the characters bra.
Short Skirt
A skirt that just covers the characters panties.
Both would be embarrassing to be seen in - more so without a bra and panties underneath - so slows the rate of confidence recovery.
To balance that out maybe it could be put on and removed faster then average clothing (If using the standard black shirt and plaid as the base line then these could be 20% faster at dressing / removal as an example).
Could make a copy of the standard shirt / standard skirt and edit the copy to speed up the art creation side of this clothing suggestion.
Robe
A loose fitting robe that covers from neck to toe.
Boosts confidence recovery but also allows faster flashing - both revealing and hiding - in the interests of keeping with the theme of the game: Exhibitionism.
Rag Shirt
A tattered shirt that is better then nothing.
Boosts confidence recovery but only slightly.
Rag Skirt
A tattered skirt that is better then nothing.
Boosts confidence recovery but only slightly.
The 'rags set' has the unique effect of having a percentage chance to be 'destroyed' (a replacement will spawn in the characters wardrobe) if conditions are meet:
Interacting with it after its put on (10%).
Flashing while wearing it (20%).
Environmental hazards (30%).
I was thinking the rags set could be unlocked by searching piles of garbage instead of by purchasing or having it given.
Environmental hazards
As the name suggests, Environmental hazards are hazards in the environment at can cause the character to lose some worn items if passing through a hit box some of the time.
Example:
Crawling through a hole in the fence may cause the characters skirt to get removed and drop to the ground where it can be picked back up.
In the same example if wearing a rags skirt then there is a 30% chance for the rags skirt to be destroyed (removed from the current instance of the game map) instead of dropped.
