I did the onesie thing as well (just make sure you get the right size, the newborn size isn't always long enough - or wasn't for Winston who's 12 inches long.)
The bad side to the onesies is that it doesn't allow the area to breathe, so constant wearing isn't always good for healing. If you have a craft dog, sometimes they can get out of them. (Winston managed this a few times, without even unsnapping it!
I just picked up a plastic e collar for Winston to wear part of the time. I considered the inflatable ones that petsmart sells, but I heard a lot of them leak or pop so we did the old-fashioned route.
If you'd like a collar to stop the licking, one of YT members makes fabric e-collars that are a lot more comfortable and you won't have possible sizing issues it sounds like you might have with the bitenot collars.)

Took a better look at those bitenots - did you measure her neck? the smallest one has a length of 3.5 inches, so if her neck isn't at least that long you'll have issues with the plastic stretching her neck and possibly hurting her. The plastic must be semi rigid, so it prevents them from turning their neck and irritating things vs. the traditional cone. Too long would hurt her neck I'd think?
