Collar type struggles

I’m looking for a nice 1.5” collar and not sure where to go

I have a golden retriever pup who just doesn’t look comfortable in a 1inch collar, she has a martingale at a 1.5” as she used to back out of a standard collar but has since stopped that behaviour and now I don’t particularly need to use it especially as I don’t expect her to walk in a heel 24/7

It’s so hard to find collars that wide that aren’t necessarily heavy duty tactical collars that I think would look too bulky on her or martingale collars

I’m looking at layered biothane collars but can’t decide if I love or hate how they look
