If you want to stand out at a party red clothes are a pretty safe trick while black clothes are prefered if you're going for a more subtle look. Always remember that less is more. You don't want to look like a birthday cake even if you're going to a birthday party.
Tube tops and straps
Tube tops are, at least in my opinion, one of the best garments out there if you want to look glamorous and dressed for a party. There's only one problem though - the bra. Using a regular bra won't work because the straps will take away the whole point behind the tube top. A bra without straps can make you nervous and you often feel uncomfortable. There's nothing that can ruin the impression like the pulling and constantly checking your clothes. You have to look comfortable to look good! So I always recommend transparent straps, also known as clear straps. Just replace the straps in your bra with these. They are almost invisible and you can wear your regular bra and be as comfortable as always!

Party shoes
The rhinestone sandals are so incredibly cute! They just seem to scream "party!"
If you're going to a house party or don't want to torture your feet, try barefoot style! I've done it a couple of times and it both feels great and looks cute. Of course, don't forget the toe nail polish.
Party dresses
A simple type of dress is almost always right at any kind of party. You can't go wrong with a classic, black dress. If you want to add something more to your look, put some effort into finding great accessories.
