Midnight mistake

Years ago i bought a ballgown...I didn't have a ball to go to but I saw it, I liked it, it fitted and it was £12 in TK Maxx.
It still hangs in my wardrobe, tags still on, never worn and I doubt it would fit me now. However it is Midnight blue with sparkly stars, so fitted today's challenge word - midnight.
Hubby stills winds me up about it :-)
