Anti-Radiation Maternity Tank Top Cami Pregnancy Protection Shield Silver 800629

I just purchased this, as I am about 1.5 months pregnant. I was searching for some clothing item to keep my belly safe from all the radiation we encounter on a daily basis from cell phones, microwaves, wireless internet and the likes.This little camisole is actually nicer than I expected. The fabric is very shiny, a pretty silver color shine, so it could be worn as a top by itself, as shown in the picture. But it is still soft enough that it can be worn underneath other clothing as an undergarment.HOWEVER - beware of the size. I am a size SM in US charts, although I am busty (38") - the camisole fits nicely and is quite lose still around my waist line, but in the bust, it is just right. That said, I don't feel like my 7-9month pregnant belly will fit in here. Seems like the 'one size' fits all is modeled on Asians, who tend to be petite.I am unsure until how far along in my pregnancy I will be able to wear this, as I can see the chest area getting tight fast.... I am guessing if you reach about 40 inches in chest size, this camisole might start to get hard to get on. It is only adjustable on the shoulder straps, not on the circumference at all.Otherwise, for now (and since most women don't get a big belly until month 6-7), this is a great buy. I tested the item by placing my cell phone in it and after about 20 seconds, the signal had gone from full force to one bar only. So this works for me.I was also looking to see whether this would protect me from radiation when flying in a commercial airline (cosmic radiation), but it doesn't seem to say tat it will, seems like this protects you only from Electro-Magnetic waves.
