I LOVE real easy's
They are a great fit on both of my twins, although they are still in size small. I think they are a much better fit than fuzzi's and much trimmer, although I have never had to boost them and always have to boost fuzzis (if i bother using them).
The only downsides IMO are the crap colours, although the cow print is good, and you do have to make sure that you tuck the frill at the back in as it has a habit of sticking out.
ETA - Riley is quite skinny and almost in the smallest setting, Lachlan is a bit chubbier and has two snaps to go before he needs a medium. They are very generous in the sizing.
