>>56349684I don't know about a guide, but it really depends on what type of dress you be comfortable wearing, something athletic looking like this
>>56347497, or something long and flowy like in my pic, or with shorts underneath like in LGPE. White gloves, aqua earrings, another thing that the LGPE redesigned added, they really made the yellow messenger bag work will with the outfit
For a wig, warm brunette, mid back length and wavy. I'd also recommend carrying a plush of one of her pokemon, Blastoise, Jigglypuff, or Ditto
