DM and Fetchez- I would definitely need something forgiving. I have a bit of a stomach wobble situation which needs working on before the wedding. Was rather hoping the ruffles would hide tummy acreage. (Bum and cleavage are passable).
Planetpotty, Pinkflipflop and whostole- glad you like it :) I fear it wouldn't look like that on me though!
Kandy- good point re polyester, hadn't considered that.
Cyb- I did think about that, which was why I checked the BM dress colour with the bride. But I did wonder whether maxi dresses were so ubiquitous nowadays that nobody would really notice it? Knee length looks awful on me- I fear showing my legs in public in case people think I have stolen them from Dennis Wise.
Onlyaninja- can't tell from the photo, think I'd need to order it and see. Any split above the knee might be a bit too racy .
LittlePanda- that's quite spooky, because I did see that purple dress in the Debenhams sale a couple of weeks ago, but the only one they had on in the shop had a jammed zip and I couldn't try it on. Maybe I should order it and try it?
Fishy- TBH I feel short and stocky whatever I wear, but short dresses tend to exacerbate the problem. The wedding is in quite a glam small country spa hotel so the dress would probably not be too out of place.(Me, on the other hand...:))
