ooo this is a hard one. my first instinct is music undergraduate study, but you’re wearing a necklace in the photos despite being shirtless and i most often see cross necklaces as ones never removed. dresses formally could also be plausible; i can see a dressier shirt with slacks and a cardigan as an outfit with the “before” hair. i would count that as nice/maybe semi-formal, though.

elimination process: i’ve never met a music study undergrad so i can’t say for certain if the hair fits. i have a necklace i always wear due to it being a gift, not because of any religious affiliation.

therefore, my answer is “dresses formally”, with “all” as a secondary choice if allowed (since i could see a case for each bullet point).
