Shade77 - I took some stupid selfies this morning.
Hopefully this gives everybody a better idea of what these are about.

These are being worn with a ABU little pawz. The leg and arm shots show the slack on a size 18 being 5'9" (69") and weighing 172 Lbs. I found if you take a string and thread it through the zipper it makes it much easier to zip all the way up. Once you get the zipper up you have to secure the zipper stop and zipper cover. To take the PJs off, just unbutton, thread the string through again, and pull down. It is a bit of work, but totally worth it. I think i'm going to order a size sixteen as there is some stretch left in the weight area and that might resolve the slack problem in arms and legs area.
If anybody has had these long enough they might be able to comment on how they handle once they have been washed a few times? Do they shrink? Do they stay the same? I wash all my baby clothes in cold water, low spin, and ultra delicate or air dry.
I have noticed the back of the collar makes sort of a V shape in the back of the neck making the zipper even further harder to access, so this might be a problem if you go a size down. You will also notice that when you first sit down the zipper length in the back will pull in the middle of the diaper kinda giving you a bit of diaper wedgie. (IMHO this is kinda cool since it reminds you the diaper is really there)
Again, hopefully this helps everybody shed some light.
