Preshrunk cotton may minimally shrink.
More Info: The process of preshrinking a garment greatly reduces the amount of shrinkage you can expect from a cotton garment, but it may still shrink slightly. Unlike an untreated cotton garment that may shrink up to 20%, cotton that is preshrunk will fare much better. You can still expect the garment to shrink slightly at 2-3%.
