Girlfriend bought me speedo for vacation. What to trim?

22 yr/old male. My girlfriend and I are going to italy in less than a month and I mentioned bringing an old speedo I got a few years ago. She said she would love it if I wore one, and even told me she ordered me a new one. I love wearing them, and want to make sure I really wow her. I workout a lot so being in shape is not an issue. I have some hair on my chest, lower stomach, and thighs, but it's not super dark and bushy. Any advice on what you would trim before wearing a speedo and how much?
