Hello miraculers ! First of all I wanna apologise for those really bad pics I took , but it's dark and I couldn't find those 2 pictures on the Net so I had to take care of them while I charge my phone ( taking pictures from the laptop ... Not a good idea ... )
So we can see here a new design of Ladybug and on the backround we can see a new design of Marinettte and Chloe !
Why is this a spoiler ? Well of you look at the first picture , Ladybug has a belt with her symbol ... Well ... She only has a belt with her symbol when she gives Tikki a magical macaroon to give her a new super power , so that means that this costume has to do with a new power she will have in season 3 ! Why do I say season 3 ? Because the description of season 3 says clearly that we will see new powers !
In the second picture we see Marinette and Chloe with other outfits and hairstyles ... Marinette has a pony tail and Chloe has a pony tail too , but it goes to the right ! And also they both wear skirts ! And if you see clearly ( well I don't think so , because it's really bad taken ) Marinette hangs her design's notebook , so the way they're dressed may has to do with fashion !
Those are my theories for these spoilers , stay miraculous ! Bug out !
