National Plus Size Appreciation Day was October 6th, 2019.
The reason you didn’t see it anywhere is because it’s not that well publicized!
Well… and it was a Sunday and those national holidays that are more niche and less recognized statistically get more recognition on weekdays.
But, a site sprouted up, this year: www.plussizeappreciationday.com!
The site asks for people to collaborate with, sell their items, share their blogs, etc. Check it out and see how you can collab! And BE BOLD!
