I wanna get this game because i played fallout 3 and i didint like it because there was really ugly hairstyles and dresses.
I was wondering i in this game if you play as a lady will there be more pretty hairstyles and dresses?

This is a post-apocalypse role playing game. Not Fashion Princess 2

But on a non-sarcastic note, I'm pretty sure that all the hairstyles are the same as Fallout 3, the male ones certainly are. There are a few "upper-class" dresses, but not much.

Then im happy.
also is there more towns in this game?
In fallout 3 you couldent wear the few pretty dresses they had because they had low defense and the mean fly things kept killing me.
because if theres more towns you wont have to go to the wastes as much.

The clothes in NV are still no/low defense. Unless you get the PC version and use the GECK to make yourself an argyle sweater outfit with combat armor DT.

Can't answer the more towns, since I haven't played FO3.

Can you be a lisbian in this game?

Playing games to wear pretty dresses....
I think you're doin' it wrong.

While I have not tested this yet, I have found 2 lisbians in the wastes.

two sidekicks are gay, one male and one female. not used to having gays in the game. i haven't used confirmed bachelor much so i don't know how many gay males there are.

Yes, if you can have 'six' in it. You just hear it from what I heard, and I'm pretty sure you can have 'six' as well if you're a girl. So yes you can go lisbian.
