I thought that... I normally avoid polyester at all costs BUT I will say that this dress doesn't feel like Ethel Austin polyester IYKWIM... It is very soft and nice to the touch. It doesn't crease and falls beautifully. It doesn't make you feel sweaty... I haven't tried washing it yet as I've only worn it a couple of times for short periods, but despite the website instructions, the SA told me she washed hers, no problem. I wouldn't normally, as I said, invest a lot of money in polyester, but the pattern, colours, design and cut made it worth it for me on this occasion :)
