My first thought was either discoid lupus or pemphigus. The symmetrical rash around the eyes and the nose involvement (it looks like there's irritation around and under her nose?) are red flags.
My second thought was mange. I'd want a skin scraping done ASAP. Can't believe the vet wouldn't have already done that.
Allergies -- Possible, particularly given how common allergies are in dogs. But my guess is that something else is going on. The symmetrical eye involvement just doesn't look like allergies to me. What kind of testing was done? I've had dogs tested via the blood method and was really pleased with the results and confident they were accurate, but the gold standard is skin testing by a veterinary dermatologist. Was she on any type of medication (steroids, antihistamines) within a week or so prior to testing? That can mess up the accuracy.
Having her lay on a sheet or wear pajamas sure won't hurt, but it's no guarantee with contact allergies. Dogs can be allergic to such common fabrics as cotton and polyester (which would likely be in sheets and pajamas).
Personally, my advice would be to consult with a veterinary dermatologist. Spendy, yes. But probably less spendy than having a general vet play the guessing game, and likely to get the dog relief faster.
