Victoria 4 from DAZ
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).
The two straps options are supposed to be used separately! If you use both straps together, there might appear unsightly pokethrough
There are separate custom made fits for Emma, Vanessa, Didi, Alice and other characters in the non-crosstalking version - you do not need to dial all the numerous dials to fit to their body shape.
There are several body parts in the skirt of the dress to help fitting it to various poses. You can 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 figures.
Due to the loose nature of the dress there might be pokethrough - numerous adjustment and loosening morphs can help with pokethrough in most cases.
