People about Cosplay...
For me, cosplay is the art of bringing a fictional character to life using yourself as a medium. As people have already mentioned, cosplayers put a lot of money, time, and energy into their craft. Some will go to extremes to lose weight or learn a technique outside their skill level just to try and cosplay that character.
I really love cosplay and I find it is a mirror of how you will treat a lot of things in life, whether that is your job, your relationships, etc. The typical time and project management questions always appear (“Can I finish this in time for this convention?”, “Do I have the resources?”, etc.) but also some that you may not expect (“Should I just stitch this poorly to save time?”, “Will cutting a corner here affect the project later on?”, “Should I invest the time in learning this new technique and apply it to the costume?”). The way you answer these questions are exactly the same way you will answer these questions in real life.
That’s why cosplay is such a great way to make friends than other activities. Not only do you have a great excuse to geek out to like-minded people about your passions, you also can see whether or not they do as they say. You really get to know the people and can truly bond with them.
At risk of sounding like a Nike ad, just do it! Find a character you want to dress up as and get started. If you need help there’s plenty of tutorials (both blogs and videos), books, and forum you can turn to for advice, especially if you’re doing something popular. Or you can do what I did and just muddle through it yourself. My first costume I bought what items I could, mostly at secondhand stores, dyed and altered a shirt and made some simple arm wraps out of cheap cotton. I had no idea what I was doing (and no sewing machine – do your hands a favor and use one if possible) but it came out pretty well and I’m still happy with it.
These days I usually make mine from scratch, finding a sewing pattern that is somewhat close and adapting it as needed. When I can pick up patterns cheap I look for anything that might be useful and stock up. I’ve gotten unused patterns for as little as a dime before, so even if I never use them I’m not out much. I like to let other people do work for me when possible. Secondhand stores can be good for base items and even for fabric, either by cutting something apart (one of my costumes is 95% bed sheets) or if you’re lucky even plain fabric (I once found a piece juuuust big enough and in the right color for an outfit I wanted to do).
Remember you can decide how true to the source you want to be. If something is outside of your skill level or too expensive to do “properly”, you can find a way to do something. I once stumbled upon a pattern to knit Rinoa’s duster, but painting or sewing the wings on a plain blue one works too. Or you can stylize it to your own tastes. My costumes never look great, my skills aren’t at that level, but I can do “good enough”. And you’ll never be sure what you’re capable of until you try.
There’s a few things – one is that you you’re going to get asked for pictures, especially if you cosplay a popular character.
For conventions, make sure that you have a way of carrying essentials on you, even if your costume doesn’t have pockets. Perhaps make a simple bag to match your costume (same color as your outfit, or decorated with a suitable design, an example being a Jedi costume with the Jedi order symbol).
Wear your costume around before the convention, to make sure that you can move around in it, or that things don’t start slipping/pinching/falling apart after a little while. At home, there’s lots of time to make adjustments and fixes.
Don’t worry if you’re not as good as some of the veteran or professional cosplayers out there. Those cosplayers started somewhere too, and with practice, you too will eventually get good.
