What size in the House of CB Emilie Bridal dress should I order for my wedding??

I’m getting married soon and looking for a wedding dress. I really like the house of CB Emilie bridal gown but I’ve seen mixed reviews on the sizing. I’m generally a UK4, 32b bust, 24 inch waist and 5 foot 2. I already expect it to be too long

for me so I will get it hemmed but I’m not sure where to order XS or S. If you have ordered from the bridal collection or tried on the Emilie dress please let me know. Thanks 😊
