Clothes creases

[Louby]

Hi everyone, wondering if you can help!
I bought a dress last week and love it! except for when i have it on and I sit down it creases completely all over-I had it on Monday and had to iron it twice in the day and it was already ironed anyway!
Is there anythin I can do to stop it because as it stands its completely unwearable.

If you know let me know, I end up walking round all day like a fairy because I dont want it to crease xxx
