Haha, Rio de Janeiro also is too hot for me. It often happens that blouseless lolitas are overlooked there because, who can survive 40°C in full ott?
But Brasil is just too big and has many different regions and weathers along it.
That said, I'll try to answer your questions (but bear in mind that those are all my personal view of it.)
>How do you guys keep from getting sun damage? A long sleeved shirt in December seems about as comfortable as being locked in an oven, and sunscreen only lasts so long.
I'm pretty white for Brazil's standart, so I have to stick with 50SPF sunscreen when walking outdoors. I live in the middle area of the country (far from the beaches) so it's not as hot as Rio, for example. A very hot day in summer goes as much as 30°C here, so with that we tend to avoid meetups or have them at each others houses or shoppings (so that we can rely in the air conditioned and stay far from the sun).
As another anon stated, boleros are your only salvation around here. I have a collection of laced boleros to wear over my blouseless JSKs, so that I can keep fresh and do not "disturb" the Lolita Police.
If not that, Parasol is a good friend of yours.
>How does your family see EGL? Don't you get crap for being 'cheia de frescura'? Do you wear it out and about? How do people react?
My family is pretty ok with that. Before EGL I was into cosplay, so this transition was pretty easy for them to handle. Since I sew and am involved with other artistic activities, they tend to encourage me as a form of expression. And being the only one financially responsible for my own expenses also helps in this, of course.
Haha, it's been a while since I heard this expression "cheia de frescura"! I wear mostly classical and goth, so I don't really give out these vibes (that I believe might be more common around sweet toned lolitas).
I tend to wear manly outside in meetups, art exhibitions, museums, concerts and operas.
