Turning white off-white?

[kyo-o.livejournal.com]

Hello egl! I was wondering if anyone here had any experiences with dying fabrics. I recently ordered this blouse from Anna House which I must have accidentally ordered in the wrong colour. It was advertised as cream white but the one I received is extremely white with more bluish undertones and doesn't match any of my clothes!

Would it be possible to dye it just a slightly creamier shade? The fabric and lace it's made from are cotton but I realise the ribbon probably wouldn't take to it (although since it's still white it wouldn't show up to much?). In particular, I am trying to match it to the "off white" fabric that Baby uses.

Thankyou in advance!
