Is it okay to serve champagne in a wine glass?

I’m serving both wine and champagne at my wedding and can’t afford both wineglasses and champagne glasses from a rental company. There is going to be champagne bottles at every table, the wine you get from the bartender.

Can a wine glass work for both (in an etiquette sense)? Or is there another multipurpose glass that would work for both? Would it be smarter to just have champagne glasses?

Any suggestions or advice would be helpful.
