“dolce vita cocktail” attire for wedding in Italy

I’m going to a wedding in Tuscany, Italy at the end of September. I’m wearing a black suit for the wedding (required) but trying to put together a really nice outfit for the welcome dinner which is “dolce vita cocktail” dress. It’s at a villa in the Tuscan countryside. Would love some guidance/suggestions here. I’m a little under a year into my clothes/style journey and have leaned into classic menswear pieces, many with a modern touch. What colors, fabrics, styles come to mind for an event like this? I started playing with an outfit idea based on a green silk knit tie and linen/cotton jacket that I thrifted. I’m not married to these but like them well enough. Struggling to choose the right trousers though. Linen pants did not look good (it looked like a bad suit). I have a nice pair of stone high rise chinos that are a couple shades off of the jacket. Shoes - I’m thinking brown suede loafers, which I may grab from Meermin during my NYC visit next week. I also have black Alden tassel loafers that I just snagged on eBay. Some notes on sourcing - I can go to any shops in DC/Baltimore/NoVa area. I’m also going to NYC next weekend and will check out Meermin, Alfargos marketplace, and other retail/vintage. I also have a ton of thrift options where I live. Would appreciate any thoughts on the current outfit idea, or even other directions to consider or pieces to look for at thrift/retail over the next several weeks. Or even if you just want to drop some inspo links. Thanks!
