Sarah did you get the note today from the fitbit people about the new fitbit that resembles the apple watch but is a high tech fitness device ( not a phone)? Looks interesting for future, but for now my Fotbit One clip on works. I don't wear a bra either, but clip it to my LDS garment that resembles a light tshirt. It kep falling off my waistband so I moved it and that's where it stays.
