Maternity Clothes for a wedding guest

Dreaming • Mumma bear to baby boy 🧸 and expecting again 🤰🏼 💕 Dreaming always dreaming 💕

What would you recommend? I love online shopping, I’m from Australia 🇦🇺 so I may not be able to get everything unless it has international shipping. I want something fashionable, classy and nothing that will make me look bigger, I will be in my 3rd trimester when I go to my cousins wedding.
