Runs big you have to buy size smaller

The outfit I expected to receive is a short sleeve jogger baby girl set, which is currently the picture being advertised as the main picture. I didn't realize that when you scroll over, it's a completely different outfit being advertised and that's the one being shipped out and delivered. Maybe the advertising will change by the time you read this review but as of now, the wrong photo is being used as the main picture to advertise. What's being sent out is a long sleeve outfit, more like a sweat suit.
