Hi there. I bought an all lace dress in the January sales but I haven't had the opportunity to wear it just yet. It is very beautiful but made of very thick stiff lace fabric. It is 100% polyester but it says dry clean only. It also smells a bit chemical, even after all this time. Before I wear it I would like to soften it a bit and I thought of soaking it in warm water with conditioner for 24 hours. Worried about the 'dry clean only' label though. What do you think?
