What to wear?

Hey guys, my friend Ella is having a party/dance/disco thing for her birthday and I have 3 different outfits, but the dress code is 'glamor' (Ella being Ella and doing anything to get her ass in a big sparkly dress) so which one of these would be the best to wear...
Outfit Number Uno! - This black t-shirt has a see through back and I would wear some black leggings & high heels that have golden studs on them :)
Outfit Number Dos! - The blue dress isn't exactly the same as the one I have but it is pretty similar, I have some blue strappy heels that would suit it :D
Outfit Number Tres! - Little green dress, had it for ages and I wear it all the time but it still looks pretty, again like number 2 it isn't exactly the same as the one in the photo, it has white stripes running through it.
Stay beautiful, Keep it ugly Killjoys ;)
