Oh geez. This is just my opinion, but I really am not a favor of gauchos unless worn as yoga pants or around the house! I dont think they are tacky, but it is definitely not the best look out there.
I used to see a ton of people sporting the gaucho dress pant with a tall high heel boot all the time. I still see it occasionally however, I have never sported the look myself. Was this ever acceptable in fashion? Is it still?
