Stylenanda is a Korean online clothing store.
You can purchase its clothes at reasonable price, so you might not expect great quality.
However, this shop is introduced by a famous Japanese stylist, Yukari Ota, on her blog (SLEEPING TOKYO). She says "It has pretty good quality although the clothes are cheap (http://sleepingtokyo.com/rinko/blog/?s=stylenanda)."
STYLENANDA has issued a lookbook and I saw it at a book store in Seoul.
I would say this shop sells simple, colorful, and casual, clothes. AND they are Korean style!
The models are pretty like K-Pop stars.
They also produce cosmetics.
You may want to try this shop!
