Bridal shower/bachelorette party

I’ll be getting married in September 2019! I have been to a bunch of bridal showers and I HATE them. I think they’re so boring and awkward. I don’t want to get all dressed up and have to be polite all afternoon. My mom has convinced me to have a bridal shower/“party”. We are planning on having it at a winery and the owner has told me I can set up a wine tasting for me and my guests! Then my plan was to head out on the town after for the bachelorette party portion. How do I word the invitation so that people don’t think of it as a shower in the traditional sense? It will be wine themed so I wanted to go off of that! Oh and I am not registered anywhere and don’t want gifts... so I wanted to say “bring $10 to enjoy the wine tasting and finger foods will be provided” ? Is this tacky?? I’m very laid back and we’re in a small town! Thanks!
