What is the difference between junior prom and senior prom?

I know that most junior go to junior prom and most seniors go to senior prom and that girls usually wear shorter dresses for junior prom but that's all I really know. Please help! Thanks

well you basically just answered your own question, but at my high school when i was there they actually had both the JR and SR prom both together so just one prom
There is no other difference. The junior prom is for the junior class, now other student may be there but only if their date is a junior. The senior prom is for the senior class etc etc. There is no difference in how they dress, it is formal. A semi formal would be shorter dresses and less formal. Proms are always formal!
for some schools the junior prom is like a mini senior prom the junior prom is for 11th graders and the senior prom is for 12th graders the junior prom is often not as nice as the senior prom the junior prom usually costs less, is not as nice, and not as fancy as a senior prom therefore the shorter dresses only juniors are allowed to buy junior prom tickets and only seniors are allowed to by senior prom tickets however they may bring a date that is not a junior or senior at my school we can bring a date that doesn't go to the school but they must be under the age of 20 some schools don't allow students to bring dates that do not go to their school and others allow them to bring dates over the age of 20
