Formal Dress Purchased from the formal wear section in Aeon, but I wore something else, so it was only tried on in the store. The color is navy, and it has subtle glitter that sparkles finely when light hits it. The upper part has a generous amount of fabric, and it's adjustable with a back string, so it seems like it would fit sizes 9 to 11. Suitable for piano recitals... Maximum width under the armpits is 46 cm, about 41 cm under the bust, and the length is 90 cm, but adjustable.
