This is a lovely look, I want to try something similar.
The one thing I've found with my pale legs is it helps if they match the rest of my skin, so if my face is getting color even with strong sunscreen on it, and my arms have started to freckle a lot in spite of the same, I try to at least expose my legs to the sun a bit more so I match myself.
Also I've found it easier for me to feel like going pale on gray days than bright sunny ones for some reason? I think it's the British Isles influence on my subconscious, pale skin and fog are good friends in my mind, bright tropical sunshine seems to pair with skin pigment as protection - so I usually wear something long and flowy instead for practical reasons.
I think also so much depends on cultural context. Living in countries with a huge market for 'fairness creams', and where gorgeous little girls passing by would take my arm and pet it and tell me it was beautiful, made me painfully and immediately aware of the colonial and caste implications of pale skin and how arbitrary beauty standards can be. Somewhere (and somewhen) every iteration is beautiful to someone, and somewhere, every iteration is not, and the 'why' has everything to do with history and almost nothing to do with aesthetics IMO.
