#pibo

Hi! Thanks for the question, and sorry for taking ages to reply!

Historically, 披帛/pibo and 披风/pifeng would not have been worn together, as they are from different time periods.

As I explained in my post on pibo here, the pibo - a scarf-like accessory - first appeared sometime around the Qin dynasty, really came into vogue during the Sui & Tang dynasties, and fell out of common use during the Song dynasty. Below - Tang dynasty-style pibo (via):

The pibo didn't disappear, though - it just evolved. During the Song dynasty, the pibo evolved into the 霞帔/xiapei. The xiapei became an important component of women's formal attire in the Song, Ming, and Qing dynasties (x). Below - xiapei in Ming dynasty portrait (via):

Meanwhile, the pifeng, an outer coat with loose and long sleeves, was worn during the Ming dynasty (pifeng is the Ming dynasty name for beizi). Below - pifeng (via):

So technically, it would be anachronistic to wear the pibo and pifeng together. However, nowadays people are free to mix and match hanfu as they please. Unless you're going for historical accuracy, there's no reason not to wear the pibo and pifeng together if that's what you want ^^
