Topshop red open back dress sz 4/6

A dress that feels silky and is double lined. Color is a reddish/orange. Never worn before. I’m 5’5 and it hits right at my mid-thigh. There is a gold detail on the neck strap that makes it look more elevated. Back is open. Size is US4 but can easily fit a 6 as well since it is a cowl neck and back is open there is a lot of flexibility and room
