Ha fair point about the jacket being ringmaster-esque, thats a resounding no to the jacket then?! I definitely will need something over the dress as the photos will be taken outside (unless its raining I assume) and I don't think a cardigan would be warm enough.
I understand what people are saying about it being a safe option which was my question in my op but having just gone back to work part time and paying for childcare I think my days if shopping in Coast are over for a while anyway! I do have a navy blazer so might see if that will work and if not look for other jackets.
I love the idea of tan shoes- I think nude will be too close to the dress but not close enough IYSWIM? will check out that website, thanks.
