Blanqi?

so far, feeling sexy and radiant have been far from my reality.  in anticipating the weeks and months ahead, i wanted to ask you...have you heard of the blanqi?

apparently it's supposed to give pregnant women great support for their back, lift the "girls" up, and smooth out any lump or bump that may have popped up during pregnancy.  since i'm not that big yet, i don't feel the need for support wear. but for those who have gone through pregnancy before, was support wear an everyday staple?  just wondering...
