There are actually considerable variations in fabric price, and trims can nickel and dime you to death, but the real difference is the the washes. Within the same laundry, washes can be $1 (rinse) or $25+ (these are some complicated washes.)
Of course, the country of manufacture is a huge factor as well. Go to Japan for maufacturing, and you are jacking your costs ups significantly. Go to China, or Bangladesh or Vietnam or Pakistan, and you saved yourself a fair chunk of change.
