1989: Sweetheart Sister Ponies
FRILLY FLOWER
Yellow earth pony 'sister style' with aqua mane and tail, bouquet of pink flowers symbol, pink floral earring.
To my mind, the two members of the set not released in the United Kingdom seem a bit random and thrown together. Whilst the other four all follow distinct patterns - monocolour designs, earrings that match eyeshadow/symbols/accessories - Frilly Flower and Fancy Flower have hair colours that differ from their body colours.
Please note that the clip shown in my pony's hair is NOT a My Little Pony accessory. She is just being cute for the cameras.
Frilly Flower was never sold in the UK. Because the US release did not have the same logical colour coding of earring and accessories, I have no idea what colour brush or ribbon she came with. However I am fairly sure she came with a floral brush and a lace ribbon, and that, like the whole set in North America, she was sold sealed onto card, rather than in a box.
If anyone has a Mint in Pack picture of Frilly Flower they can let me use, I'd be grateful :)
