Love and Bravery - lots of cute clothes, many with a mori girl sensibility, at really reasonable prices! (Shirt pictured above is less than US$20)
Romwe - Not all mori clothes, but stocks some pieces that would be a nice addition to a mori wardrobe, including some nice floral dresses and oversize sweaterdresses. Also sells some vintage clothes!
Crows Cloth - A number of very cool tops and sweaters, along with some interesting accessories.
Milo Creative Studios - A number of nice basics—their Classic Wrap Skirt is worth mentioning—as well as some more unique designs.
Qiujuer’s Home - Pretty clothing, variety of styles, sizes and colors. My favorite is the dress above, but there’s lots of other very nice pieces.
Sweet Cake Cookie - Sundresses and mostly other lightweight clothing in earthy tones and florals.
