It doesn't matter what you wear, as long as you're there - go for it haha.
Maybe not ao much sad as dangerous, you can get some aggressive types out at night and you could present an easy target if you're on your own. Other than that I don't think anyone really notices while clubbing, I always see people dancing alone in clubs. Have fun and stay safe!
lol i went clubbing and made out with a 44 year old **** it was ****ing sick
It's not sad but may get a little boring if you're alone.
It depends if you're willing to socialise with new people or not.
If you plan on chatting girls up all night then that's okay. If you're not going for that reason and your mates aren't there then there's little point.
