I have quite short, layered hair so it looks a bit naff when I have it up because it’s hard to keep in a ponytail/bun with the shorter bits falling out (admittedly this might be my limited hair styling abilities!). When I was a bridesmaid even the hairdresser struggled with the updo and had to use a thousand bobby pins 
But normally it looks a bit scruffy when I put it up. Fine for casual stuff or just at home, but i prefer it down generally.
