Ladies, Do you FAKE your clothing size?

When we go into a shop, We hope the outfit will help us look smaller. The clerk asks our size. We sadly tell her and she brings an outfit ...and the tag clearly shows the size smaller than what we told her.
Are you more inclined to purchase it even tho to the size marker states a smaller number?
After all it does fit; and quite nicely.
I feel we have entered the Twilight Zone of instant weight loss.
