Description

Meet your new favourite foundational piece: the Ultimate Thong Seamless from Katie Em Undies. When you need a completely flawless silhouette, this thong is the answer. It’s designed to be the most comfortable piece of no panty line thong you’ll ever wear.

The key is in the innovative seamless construction. The edges disappear under clothing, making this thong truly invisible under clothes. Whether you are wearing silk trousers, a bodycon dress, or workout leggings, your secret is safe.

Beyond invisibility, comfort is paramount. The fabric blend provides a supple, soft feel with four-way stretch, moving effortlessly as you do. Unlike typical thongs that can pinch or shift, the Ultimate Thong is engineered to stay exactly where you put it, ensuring no digging or riding up. The lightweight breathable thong fabric is perfect for staying cool and fresh, making it a comfortable everyday essential.

Available in a range of core colours (please specify colours on the product page) and sizes Small through Extra Large (Sm-XL). Due to the stretch and tendency for the fabric to relax slightly over time, if you are between sizes, we strongly recommend you size down for the best long-term fit. Please remember all sales on underwear are FINAL SALE.
