i agree with the eyelids and cheekbones, maybe she did something along the lines of what bella hadid did, got the fat removed from the lower part of the cheeks but kept her cheekbones, so the "contour" looks much more dramatic, even for bella hadid that gives her a much more older woman look compared to her sister gigi who looks much more youthful with full cheeks. & i also agree with her "paris wardrobe" aging her! she looks much better with a colourful wardrobe, & quite honestly minimalism is trending out in the fashion world, it's almost her time to shine with the maximalist, colourful princess-y wardrobe but maybe she is too influenced by her new relationship for that kind of wardrobe
i guess it could be weight loss but i think her body looked the best in 2018, i think she must have had something done to her face for sure in the cheeks & eyes areas & i'm not sure if its botox since her wrinkles on her forehead are so apparent
