There are two versions of the dress - crosstalking (for easier fit to included clothing morphs) and non-crosstalking (that mostly works in Poser - for more comfortable use with fitting the clothes to custom non-supported or heavily morphed characters).
There are separate custom made fits for many custom characters, like Emma, Vanessa, Kate, Alice2 and others - you do not need to dial all the numerous dials to fit to their body shape.
There are several body parts in the skirt to help fitting it to various poses. You can find them in the Dress bodyparts list (or make them visible via the included MAT pose) and move them front-back, side-side and twist for better fits. Best of all you start fitting the skirt to a pose by selecting the “skirt” part and twist/bend it to roughly correct place. After that use other handles to finetune the bottom part of the skirt to the pose.
You can find many adjusting morphs in the BODY part of the dress.
There might be pokethrough in various poses - numerous adjustment and loosening morphs can help with pokethrough in most cases.
The earrings are one object and include morphs for Aiko 4 headshape easier fit and movement morphs - left and right earring can be moved separately from each other. Most characters do not need repositioning of the earrings at all but just in case it will be needed - there are all necessary dials included and visible in the Earrings Parameters tab.
Most shader-based MAT poses are very dependant on the light you provide in the scene. The Poser promo images are created with the included IBL Lightset for Poser6+
