I am between and small and medium in juniors sizes, so I ordered these in medium based on the other reviews.  I find them to be a bit loose/baggy.  Now, I have not tried the small, so these may be the best fit for me after all, but compared to the model, mine hang off of me a bit more than the pictures show.  I typically wear a size 7 jean in Juniors (occasionally a size 5), so that tells me these run true to size, if not a bit big.  I have not washed them yet, but I don't anticipate a problem since I wash my clothes in cold and don't put them in the dryer.  Overall a cute look, but don't listen to those other reviewers...unless you like your clothes to look like they are falling off of you!
