What should i dress my dogs up like for halloween?

i have 2 mini dachshunds (brother and sister) and it is their 1st halloween..i am so undecided on costumes for them ... i dont want something to heavy or bulky. i also want them to sort of match. ive thought of hot dogs (one mustard and one ketchup) or frankenstein and his bride but i still dont know.. any ideas? (i also have one cat that will be dressed as a witch as of now,i already bought the costume =] ) thanks for your time.
