Most cats don't like to be dressed up. It varies from cat to cat, since they all have their own little cat personality. xD
Lucky you have a cat actually let you to dress her up in peace.
I don't exactly know what is going through their little kitty heads, but I believe those cats who put all their trust in their owners will allow clothes to be put on them. They might think whatever you do is for their own good. With that point of view in mind, you can do anything (with no harm of course) with them. Yes, on the opposite side, some cats who absolutely hate to be dressed up might somehow believe you are harming them by putting the weird stuff on them.
Some cats might actually like the "weird" things and enjoy whatever you put on them. Sometimes they might be after whatever reward you might give to them as they have learned it's always the end result if they let you do whatever.
