Answer 2

When you are looking for something to dress up as for Halloween, hippie costumes can be a great way to get noticed. The 1960s were all about great music, self expression and long hair � so have a lot of fun with it when you pick out your costume.

You can be any age and any gender to be a hippie. One of the best things about these costumes is that they will be very comfortable and you can get away with just about anything. Shopping doesn't have to involve spending a lot of money for hippie costumes, so you can buy some things and use some stuff in your closet or buy a whole new ensemble to wow people with.

Many of the Halloween costumes for hippies include tie dye, but that's not all they have. There are also leather vests, poet shirts, old concert T-s, bell bottom jeans and much more. You can pair any number of these costume pieces with your own top or bottom or decide to go for something a little more unique � especially if your old bell bottoms don't fit anymore.

Unless you already have really long hair, then you may want to consider a wig. Men and women of the 60s wore their hair long and straight. The wigs that you choose can be any color that you want � as long as they are flowing down your back! You can opt for the expensive ones that will allow you to get many uses out of them or a cheaper one if you plan on doing the hippie look for one day only.

There are many great looks that come with being a hippie. Girls can wear flowers in their hair and guys can get away with wearing flip flops with their costumes. Make sure you know how to make the peace sign with your hands and if you're having a Halloween party, get some of the music from that generation to play through the house. While it's unlikely that you'll be driving up in a VW bus, you can still arrive in style with a great looking hippie costume.
