Suggestion I
Ruqun Separates that all stack correctly on the avatar, for numerous color options. Colors should include: red, hot pink, medium pink, light pink, medium green, light green, medium blue, light blue, black, white, deep orange, medium orange, peach/light orange, and medium yellow.
The different separate type of pieces: upper garment (should tuck in under everything else), long skirt (should be the second-to-bottom layer, the shirt tucks into it), weighted ropes (the third-to-bottom layer), short skirts/waist-skirts/whatever one might call them (the second-to-top layer), belts (top layer, everything else is beneath it). Better traditional Chinese cloth shoes to look good with these, in black, gray, white, and the ruqun outfit colors.
I would prefer it to be ruquns that have the belt-type things over the waist, and no higher.
Over time, you could release numerous such ruqun sets, with different colors, some solids, some patterns, some prints, and have different places that the 'waist' type things sit on (so those who like it placed higher would also eventually get the version they like).
This would be an excellent addition to Chinese clothing options, which are currently lacking.
A corresponding EI for the first release of a set of these regular shop items could be a beautiful Chinese empress EI.
Suggestion II
I see there's a monk/priest suggestion...
Make sure you also make ones for Buddhist monks, and Buddhist nuns, please. And, for monks, do outfits both for typical monks, and martial artist ones (Shaolin should be top priority over the other fighting monk schools because it's fame, though others could be fun to add in later, such as the Japanese one).
