Yes, wire bras can indeed set off metal detectors due to the presence of underwire in the bra. Underwires are made from a metal alloy such as steel or aluminum, which can trigger metal detectors when passing through them. This is important to keep in mind if you are planning on traveling and will be going through security checkpoints where metal detectors are present.
To avoid any potential issues with metal detectors, I would recommend opting for a wireless or non-metallic bra when traveling or going through security checkpoints. These types of bras do not contain any metallic components and therefore will not set off metal detectors.
It’s also important to note that while underwire bras can trigger metal detectors, this does not necessarily mean that they will always do so. The sensitivity of the specific metal detector being used and the placement of the underwire in the bra can also play a role in whether it sets off the detector.
