1. Lady Gaga High Fashion (When It works for you, you're saying she is famous because of her fashion, when It doesn't you say her fashion is nothing special). When she attends a ceremony/show everyone is waiting to see how she'll look like so I guess It is her biggest aesthetic !
2. Lana Del Rey Retro Style (It is clear from her Discography and Videography)
3. Beyonce Glamour
4. Rihanna Urban
The other things aren't really aesthetics ..
colorful and happy ?
