I'm a big big fan of polka dots for clothes, but I think they can be very cheesy for home decor.
However, in some case, they can be very sexy!
You probably remember this room :

Oh yes! The amazing Serena's bedroom in gossip girl. I don't find the reference anymore, but I read the huge headboard was a DIY of the stage decorator. It was actually pretty cheap.
So yes, polka dots, even for home decor can be sexy! For example :
1. Ikat polka dots
Ikat is an Indonesian dyeing technique used to pattern textiles, a bit similar to tie-dye. I think you can find Ikats in Thailand, so I hope I'll find some.
Madeline Weinrib has a very stunning collection.
