I was thinking... some sites have, like asiajam a style suggestion.
but they post the links of the other pieces the items.
example:
I love a tee.
in the style suggestion they show it on a awsome skirt, with great shoes.
by adding the link with the tee.. I can easily buy the other pieces too.
It's great to look trough the catagory.. but sometimes.. the pics look a bit different. so having the direct links looks great to me.
Or add comments on the style suggestion like:
skirt is sold out. so people won't get depressed.
dunno.. It made sense when I was thinking this over XD
