When I saw that MicCostumes had a Cornelia cosplay up for pre-order last fall, I HAD to get it and I am so glad I did! The cosplay is gorgeous and so much more flattering than I could have imagined! I am a 37" bust (34DD), 28" waist, and 36" hip. I ordered a Medium and it fit perfectly at my waist when I zipped up the side zipper. That being said, my personal recommendation when ordering would be: Order either your EXACT waist size or larger. Do NOT order below your waist size. The top and skirt fabrics have plenty of stretch, but the mesh that connects them at your waist is not stretchy at all and you could risk tearing it while zipping up if you order too small. I was worried about there not being room for my chest and strapless bra at first, but the nice stretch of the top fabric made it possible! Though fair warning to my bigger chested folks, my bra DID still occasionally peak out at the bottom so the fabric might not be enough to cover larger cupped bras if you choose to wear one with this cosplay (though it could be different for larger sizes of the cosplay). The wings might need a little TLC when the cosplay arrives. Upon closer inspection of the wings, there are some open seams where you can see the wire and damaged netting. I also had to find a different way to attach the wings to myself as the clear straps it came with slip off their loops on the wings very easily. However, even with those critiques, the wings are still far better than I had expected given the price and they still looked lovely in videos! (I forgot to take proper pics in them) Overall, this is a very comfortable and flattering cosplay and well made for the price! Even with the concerns, I don't have the heart to give this dream cosplay from my childhood any less than 5 Stars! I really hope more W.I.T.C.H. cosplays are added soon!
