I saw it on IG where there is a picture. The description is "An accessory that looks like a bra but is in actual fact a bag? Yep, this innovative design is part of Belgium-designer Sarah Lévyvy_’s “Creature of Habit” collection that captures everyday life through responsibly sourced leatherwork accessories. Working with a prosthetist and orthopaedist to create shapes that mould to the body, the Bra Chest* bag is fitted with an adjustable shoulder strap and back belt for a comfortable fit – look to the cup to find a pouch to stash your phone.”
Must be why it's one sided!? Not sure what those of us with two phones, house keys, makeup & tissues are meant to put everything
