These are a two layer version of the simple skirt, with the elastic being held between the two layers. One layer is slightly longer than the other, with lace sewn on the hem. Nothing complicated, but still a very pretty effect.
I liked hers so much that I whipped up one of my own to wear to the city to see her!
I see that you are not shocked that it's pink... ;)
Things were a bit crazy when we got there, and we only got to see each other for a quick dinner in a crowded and noisy restaurant (with fabulous dumplings) while herding children who were cranky after a long day and the servers stealing their chopsticks, but it was nice to connect face to face. Maybe I'll take the trip solo next time though :P
