it really depends on how much hair and time you have! these are the current hairstyles for some of my solos at the moment (i have quite long hair)
modern - messy/spikey bun. it's just a normal bun but instead of winding all the hair around, leave a little bit out. then, on the bit that's sticking out, put on loads of hairspray and back-comb it!
tap - one messy/spickey bun on each side of my my head
lyrical - two small french plaits on either side of my head and the rest loose. do two small french plaits on either side of your head but intead of tying them with a hair band, use hairpins/kirby grips to pin them at the back of your head, under the rest of your loose hair.
ballet - bun with twists. do a ponytail about in the middle of your head but leave out two small sections at either side. do a bun as normal. then, twist the one section of hair and wrap it round the bun. repeat on the other side. this also works well with little plaits.
a good cheat is to just do a normal bun and clip in a hairpiece - you can get loads of differnt styles!!!
a good website to look at is cutie pie hair creations
hope this helps
