Normally I make my costume (I look more like a cosplayer than a person ready for Halloween though) However, due to lack of money, I haven't made one. Instead my grandma's going to send me a black widow costume (not the spider but a wife who kills her husband for money). My aunt who lives with her bought it for only 5 dollars at a thrift store! I tried it on already when I was visiting her so I know it fits (I HIGHLY doubt I gained weight with my metabolism)
Also... I REALLY wish I could still go trick or treating because I love candy but my town actually had a law passed that only 14 years or younger only can go. :/ It doesn't help that the police ALWAYS drive around town during Halloween, not to mention they all know me because my sister has had numeral incidents to get her noticed by the police. No crimes but... well, she's Bi-polar and has the usual teen problems.
