I'm hopeless!

I'm leaving for camp Friday afternoon and returning sometime Sunday afternoon. I just crammed 3 pairs of shoes into my suitcase and (obviously) plan to wear a pair to camp as well. 4 pairs of shoes for approximately 48 hours. (To be fair, one of the pairs is a pair of flip-flops to wear in the shower.)

I hate packing for things when I'm not really sure what to expect. I feel like I have to pack enough stuff for anything that could conceivably happen. (E.g., "What if I spill something on my khaki skirt? Maybe I should take an extra skirt...") My little suitcase doesn't hold that much stuff!
