Layer your blazer with buttons downs, t-shirts, or a colored shirt and sweater combo to create a multitude of smart casual looks.
Always best to ask an expert — as I thought it may be a little too dressy!!! You can incorporate many casual staples such as the hoodie, T-shirts, jeans in the smart casual, and sweatshirts which gives you the flexibility of choosing from your favorites.
Smart casual attire is a dress code that combines well-fitting, polished business wear with elements of casual attire—think blouses, polo shirts, button-downs, chinos, dress pants, dark-wash jeans, and polished, practical footwear.
If in doubt, err on the sharper side of things.
