If you dream seeing animals wearing expensive man-made clothes, it can mean you are going to waste some money on frivolous expenses. Animals do not need to wear clothes, and if they do need clothing to protect them against adverse weather, they do not require expensive clothing. Cheap, functional clothing will also do for them.
Dreaming of spending money on un-necessary items means you are showing off to other people in public. You might be having a big ego, of the opposite. If you have an inferiority complex, you might feel the need to over-compensate by showy behaviors.
