GREAT outfit on you, CarolS! The jewellery adds back some glam
It's the sneakers and the faded denim jacket that dress down the look most. And since you weren't wearing a ball gown with formal heels and a denim jacket - the resulting visual is CASUAL.
Dressier shoes and a dressy jacket would have dressed up the outfit more - and in an easy way with what you already have. Simple switcheroo.
That said, know that you looked fab! And now you have plenty of suggestions on how to create a dressier version using similar components.
Hope you had a great Passover!
