My son is 6 mon so his godmother purchased the LARGE. I was thinking they were "close" to a size 3 (per other reviews) and I could even squeeze him in these if a lil small ...since they are fabric.  I would think that the LARGE is not even a true size Infant 2.  I can only image how small other sizes are.  These are for a newborn.  Not worth returning for $8.50 so they will be passed onto a cousin. Again...VERY SMALL.  Its a shame they are so cute in person.
I gave it 3 STARS because STYLE is a 5 and FIT is a 1.
