I can only speak from someone living the West Coast of the United States. During the summer, it’s probably about 1/3rd of girls are braless. That number varies by age group of course. But most people don’t care and plenty partake in the “free the nipple movement”.
I did the beta version last month. It was 10 days from hitting submit to getting it in the mail. Standard processing. Hopefully they’re able to keep processing times similar with the roll out.
