I bought the sling off of babysteals for half the retail value. The slings are sized by weight and height and should fit a little snug. I bought it because the fabric was really lovely.
The sling works really well, and the way you snug the baby in by folding the sling over your shoulder works nicely. I keep it rolled up in my diaper bag for short trips in stores. I also found it PERFECT for airports as the babe can easily be taken in and out and it doesn't take up very much room when you are not wearing it (unlike, say, the Ergo). While I don't use this sling as much as my other carriers, its small size and easy on and off makes it useful in ways that my other carriers are not.
