The first picture is what I've always had. French tips, square shape with shellac glitter topcoat.
However I was persuaded to have a colour for Christmas, and I also decided to change the shape.
So I now for Christmas I have coffin shape nails with a red glittery shellac. I LOVE the shape and the technicians in the salon even said the shape suits me better. And I'm so glad I went for a colour. I can honestly say I'll be sticking to the new shape (I'd like a stiletto but I have a 2 year old so probably not too wise). And I'll also be sticking to colour instead of French tips.
(It's the first time in years I've had anything other than French. And the first time ever I've had a different shape, and had my whole nail painted, not just the tips painted).
