Fabi, love... I like the little black dress with the shoes. It's true the dress is elegant, but that's the beauty of accessories... to change the "look" of the dress... I prefer this and then adding your leather jacket... preferably a black one...
Makes it less girly and more wearable for more causal events... then you can wear it with a blazer and classic pumps for a more formal occassion...
Try it with a denim jacket, brown ankle boots, brown belt and a brown purse...cross body or boho will give it a more casual look... maybe out and about at the mall or something... have fun with it... that's the beauty of clothing... it's not permanent... you can take it off...hehehee
