The question that I get asked a lot is "Is the suit the same as my jumpsuit?" The answer is yes. If you have ever seen the movies Rocky and Rambo, or even the Rob Reiner movies then you will notice that most of the time (like in the case of Rocky) you see someone wearing a very similar colored jacket, usually either a black or navy one. The reason they are so similar is because most suits are designed to be worn together and not separately (like my mum would always say to me when I would try to wear my dress together from Woolworths). So if you are going to be at a big dance event and you are wearing a different coloured jacket than everyone else at the event then you are probably wearing your outfit and not your suit.
Now if you are at a costume function then it is very unlikely that you will be wearing a suit. Why? There are many reasons why people choose to put on a costume (or a costume suit) instead of a suit. One reason is that it makes them feel more comfortable than if they were just wearing a plain piece of clothing like Left On Friday Promo. Another reason is that people who choose to put on a costume can then express their individual personality or character with their costume. Some people like to go as the Hulk, while others may prefer to go as Superman.
Is your costume the same as my playsuit? The answer is no. In the last paragraph I implied that because you are wearing a costume that you are wearing something that is the same as another person's suit, however this is not always true. You would not wear your father's suit to your son's college graduation party would you? And you would surely not dress up as a pirate to attend your daughter's homecoming celebration.
