Your little daughter is as cute as plum pudding anyway! You could send her out in a potato sack, and everyone would coo. (In between telling you off for putting her in something so scratchy.)
For her first Christmas, give her something festive to wear - a gorgeous gingerbread dress or Santa's Little Elf costume. That way, when all of the cameras are flashing, you can be sure that she matches the occasion.
There's lots of Christmas dresses for baby girls to choose between. Just have a look at this collection here.
