A T-shirt dress may not sound ideal for a wedding but this was is inflused with subtle glamour and is perfect for the bride who wants a happy medium between casual and dressed up. The satin-backed silk crepe has a vintage feel to it (think an update of Angelina Jolie’s Good Shepard gown) with a fitted shape and an inset waistband. Casual doesn’t come cheap though – it’s $995.
