I contacted their customer service to work out my shoes size, they were very helpful and were able to change my order. I just got the shoes this morning and they are great! A little bit tight but nothing some socks and a hairdryer can't fix. I'm so glad I didn't get the next size up!
The shoes are a perfect colour to my wedding dress, although I was a bit concerned because the shoes looked more creamy on the website. But they are actually a light ivory. Thankfully they match perfectly!
Thanks JJsHouse!
