My first ever LoRA, i think it came out pretty well, you might want to lower the weight a little (0.7 - 0.8) with certain style LoRAs if they clash too much
Activation tags: a1ohto
yellow hoodie, shorts, shoulder bag for default outfit, yellow hoodie tag only generates the hoodie so you need shorts tag (which absorbed her socks and shoes as well) for the rest, and shoulder bag if you want it to generate her bag.
pinafore uniform tag generates her school uniform pretty decently but you might want to specify with navy blue dress, green necktie, white collared shirt if its too inconsistent
I tried to get it to generate her multicolor pen with 4colorballpen but there just weren't many images with good angles of it to make it work
