Well, just like if you put too much conditioner in your hair...your clothes will feel a bit on the heavy side, and it may not feel quite as soft. Luckily, I know just what to do if you use too much fabric softener and that is to just toss it back in the washing machine and run a rinse/spin cycle. You shouldn't need to completely rewash those clothing items, just think about it like how your hair would feel if you didn't wash enough of your conditioner out...same with your clothes, just rinse again and dry and they'll be feeling great again in no time.
