To be honest, you shouldnt be nervous at all. Olive garden is not as 'fancy' as you think. I see people in very causual clothing too, such as jeans. But since its a romantic night, you should wear a summer dress or something cute like that. Wear trendy accecories and you should be fine. If you go too formal, people will stare thinking youve never been to a place like that.
Since Ive eaten most of the things on the menu, I would suggest the 'Tour of Rome', you can either share with your man or take the leftovers home, cause it is a huge serving. The shrimp scampi is always a winner as is the chicken alfredo. They serve a big salad with breadsticks before the meal anyway, so you will likely be stuffed by the time you leave. You'll be fine, and dont be nervous dear, just enjoy your night out.
