That dress is lovely moonpie! Go for it, if you like it!
I would look a tit in it being a larger lady.
I ordered this at the weekend:
Which I thought I could wear with either tights or maybe slim leg black jeans depending on it's length and heels, with a nice clutch and some jewellery I hope it will be dressy enough. I really like it so hope it fits ok when it arrives.
Thats for the night part of my hen do, not sure what I'm wearing during the day yet.
