Different Miu Miu box

Hi ladies!

I've bought a pair of Miu Miu sunglasses off eBay UK a couple of months ago, and it seemed really authentic.

But I've just seen some of the Miu Miu boxes and mine is different. The ones I saw have the words printed on a white background and stuck onto the light pink/orange box. The brand name on my box is a bit off at an angle too.

Could it be a fake? I did try to get it authenticated in this forum but no one is familiar with designer shades.

The Miu Miu boxed came "wrapped" in a grey/silver box too, and the casing is in olive green.

And here's another pic which I took much later after I received it.
