I love showing a bit of shoulder, its a great part to show off when you are lacking other bits. You dont have to bear all to be beautiful. Thats what I say.
This dress is really inexpensive from Missguided, and I can totally imagine wearing it on one of my holiday adventures. I also Find Red is a great accent to a monochrome pallet, especially on the lips.
