Recommendations for dealing with an overly tight body suit neck?

[HellsBells]

Hi wonderful people!

I have a full body latex body suit: it's really terrific, except for the fact that the neck hole is a little too tight for comfort. To be clear, the suit zips up from the crotch to the neck, so I can wear it with the zip undone a little. I would of course like to do it up the whole way. Any recommendations? I was thinking some kind of hard wearing collar to go underneath.

Excited to hear your thoughts!
