I’ve got a friends party coming up and I almost never get dressed up. I’m late 30s, size 8, pear shaped, 5ft 1, hate the tops of my arms and thighs so needs to be at least midi length with sleeves. All I’m seeing are dresses that will age me more than I wish to be aged! Or are a bit too day-dress. Any suggestions and links would be so helpful. Will spend up to £100. Happy to buy from vinted.
