Bought this pretty Natasha dress last year and have worn it 2-3 times.
The sizing is Medium - which is roughly a size 10, but it is quite roomy
The lovely bodice
There is a slight coffee stain on the inside of the front of the dress, which should be able to come out easily, it is not noticeable when you wear it.
I purchased this for $150 at a sample sale last year, selling it for $80 - pick up in Sydney, or plus postage (should fit in one of the larger satchels)
