First: Vampires should not be affected by tge sun if they are in any type of (fully covered by) shadow. thick forests should offer shade with few sunspots that need to be avoided. Sun rays do a crapload more damage but vampires are warned before they exit buildings.
If a vampire is fully clothed from head to toe in thick clothing then they should be protected ( hood, boots, robe).
I hate how ugly vampires get in such a short time, i want to maintain my normal looks, except pale skin.
Please comment and add ideas. Feel free to disagree on anything i have already mentioned.
