A MOTHER-OF-ONE wants to match the record for the world’s smallest waist – by shrinking her middle to a tiny 15 inches. Sarah Vaeth, 43, of Portland, Oregon is a painter with a passion for extreme corseting. Since 2014, Sarah has managed to reduce her waist size to 16 inches and now aims to match the world’s smallest waist, which currently measures at 15 inches. Sarah wears a corset almost every day for 16 – 20 hours at a time.
