Dress ideas for a small civil wedding please

Hi everyone. Looking for advice on dress shopping for a small civil wedding. I'm an older bride (45) and it's our second wedding, so a very small and simple affair at Leeds Civic Hall. I'm not going for a typical bridal gown and have scoured Etsy and Pinterest for ideas and found some gorgeous ideas, just reluctant to buy without trying on first. Thought I'd ask on here to see if anyone had any ideas for dresses and where to get them from. I'd like something fairly simple and modern. Also, I'm in West Yorkshire if anyone can recommend shops (other than High Street ones) Thank you 😁
