For the ladies, I can say that my delving into the product indicates that it comes in sizes from 32B to 44D. Apparently, it comes only in the color red; at least, no other colors were illustrated and there was no provision to order it in other colors. This might merit caution regarding what kind of outer garments you wear; on the other hand, it can be a little daring to wear one of these under a light-colored blouse or t-shirt. Nevertheless, X-ray technicians, microwave users, and others who use radiation-generating equipment might consider this undergarment, both for its stylistic and practical value. This device is especially useful for those who might be exposed to serious doses of radiation in their workplaces.
The product, using the slogan "Be Sexy, Be Safe, EB" has a radiation sensor incorporated into the body of the bra. In the event of an emergency, a change of color will take place in the upper opening of the sensor’s pocket located under the front clasps of the brassiere. If the top opening (sensor strip) has become a darker color than that of the lower opening (service life strip), this signals that it is time to convert the Emergency Bra into face masks to use during an evacuation. A possible drawback is that, in order to check the color differential, you must undo a few blouse buttons in order to see the front clasp of your Emergency Bra. This might be mis-interpreted by others; still it is a remarkable advance in radiation safety. Perhaps OSHA and the military might consider these to be essential safety equipment.
My suggestions: come out with the Emergency Bra in colors in addition to red; and expand the size offerings to include demoiselles fitting more comfortably in A-cup sizes.
