I always recommend Lucy Corsetry.
She’s on YouTube and Instagram, and at LucyCorsetry.com
She has the largest corset database known, tons of knowledge on corsets and waist training, and assists with corset information for beginners as well as corset sizing.
I found her back in 2013 when I first started my waist training journey.
She taught me everything I know from her YouTube channel! 🙂
If you’re looking for other corset wearers, I recommend looking on Instagram.
Search #corsettraining #realpeoplerealcorsets #corsetsofinstagram #steelbonedcorsets #corsetcontent ETC.
Also check out the people I’m following on Instagram! 🙂
Reddit has a TON of people who wear corsets & answer corset related questions.
