It's a nice dress OP, love the red and black. Agree with some others that it 'could' look casual; for example I'd probably wear it as a day dress with tights and ankle boots, but absolutely it has great potential for evening wear of dressed up with the right footwear, jewellery, hair/makeup. I think it will look lovely and is a great choice for the time of year too (hooray for sleeved dresses).
Have a fab evening OP!
