Based on the reviews that said these are true to size I purchased a size 6.  They're a little snug, but I also read that the plastic stretches out around the foot a bit so I'm kinda counting on that to relive some of the tightness.  Each shoe comes with its own dust bag, and also a larger dust bag for the pair which is nice to keep them scuff-free while not in use.  Comfort wise, all tight fitting areas aside, these aren't too terribly uncomfortable!  These are super beautiful and will definitely assist in my figure competition in a few weeks.
