Of course it's ok silly! You're pregnant. Like sarahemccormick said, wear some comfy pants with a nice top and a sweater. You could do a skirt or something as well. Just be comfy 😋
Maybe some nice pants or even maternity jeans with a nice sweater. You are pregnant, I'm sure they will be forgiving ☺ Dress it up with aome jewelry or accessories like a scarf and you're god to go!
