I was attending one of my best friend's Birthday dinner. She was making a simple, private and intimate party. So, I choose to wear a simple dress with a random floral pattern from Topshop. Wearing a dress like this, you do not need to put on any necklace since it is crowded by itself. But you need to wear some accessories on your hand so you won't seems too plain. Big and simple earrings will help too. As for the bag, I'm hanging a small messenger sling bag, it is hidden behind my body if you can see it. Sorry I did not take a proper picture of the bag :(
