I find dressing casually but nicely is much harder than getting into more formal attire. I'm 35 with a youngish face, so I can get away with both older and younger looks. Here are a few of some of my basic casual looks, please share some of yours as I'm stuck for ideas: 1. Un-tucked/Tucked shirt with jeans, can be formal or casual shirt, but is mostly a formal shirt, as I don't have many casual shirts. In winter I put a sweater on top; on a colder spring/summer day a linen jacket. If the shirt is tucked in I'll dress it with some designer loafers (Gucci, Tods, Prada, etc.) and a designer belt (Hermes or Gucci) 2. Shirt tucked into light linen/cotton trousers with a web belt and suede shoes And one I've started recently due to the heat 3. Linen trousers with a long sleeve polo shirt un-tucked and suede driving moccasins. I cannot bring myself to wear short-sleeves, it just feels wrong.
