Absolute garbage!
You can put one of those under a lot of western clothes, we have great big coats of our own that can hid bomb vests AND AK47's etc.
Have a look at
From hijab to burqa - a guide to Muslim headwear - Channel 4 News for a guide to what they are.
Then have a google for a snorkel jacket, big padded squares that make it up.
That would be less likely to show a padded undervest than a burka.
And less conspicuous in the west.
It's more indicative of the way the menfolk oppress the women and treat them.
Heck, I find that a lot of them are just so ugly that in reality I'd not want to see their face anyway, but I don't think "she must have a bomb or gun under there".
It's the ones with the backpack that says "Does my bomb look big in this" printed on the back that you have to watch out for
