She finds a good excuse to leave the girls during the dress event, she moves a block further from the wedding dress, she meets aiden with the bag and the suit (1st image), she find another shop nearby to change and she goes back to Aiden (2nd iamge).Sorry but it is well marked she meets Aiden a block further. In the first image (therefore the meeting) it is not a block further.
I don't get your "In the first image (therefore the meeting) it is not a block further." That's the meeting point they decide and that should be 1 block from the wedding dress shop. We don't know where that shop is, so we cannot say from the image, it's what L&P said. (ie the building we see in the background is not the wedding shop)
