Well think I was 23 when I got my fursuit so its the right time! buy NOW!
Most builders wil work with you to make a char sheet if you want, something thats close to yoru character but also suitable to be made into a suit.
transporting isnt as hard as you might imagine, a case bag or otherwise just something to hold it all together and keep it safe. Really depends on the construction of the suit, if its foam then its not that easy to damage anyways. Mesh and other things need a stronger case to help keep the shape. I just have a very big bag with wheels like some uber hold all thing which fits my suit and my clothes for a con. Akino knows me so knows Im not the tallest person around and if I can manage a bag the same size as me accross a country to a con you can manage it too
Storing, hmm I guess most people hang them up in a wardrobe like any other clothes. As mines a partial it cant be hung anyway so I have a large protective drum it lives in.
Cleaning well if you download the original CF2008 con video I think part 2 is mostly all about fursuits acting and includes washing. Again really depends what your suits made from, at cons suits are usually cleaned in the bath or shower with mild cleaning agents and left to drip dry. Keep a brush with you to fluff the fur out again.
