Everyone's aesthetics and opinions on clothing matching are subjective, so there is no fixed answer to what kind of clothing Mencius should wear. Outfit matching is a personal choice that takes into account factors such as personal figure, temperament, preferences, and occasion.
The white bandeau dress itself is an elegant, pure style of clothing that is suitable for showing off the femininity and modesty of women. However, everyone's ability to handle and fit clothing is different. If Mencius didn't highlight her temperament in a white bandeau dress, it might be because the outfit didn't quite fit her personal characteristics.
As for the suggestion of a bandeau dress with a miniskirt, this combination can really show a stylish, energetic style. However, whether it is suitable for Mencius also needs to consider her personal preferences and occasions. In some formal or solemn occasions, this combination may not be appropriate, while in some casual or fashionable occasions, it may be more appropriate.
Outfit matching is a process that requires a combination of factors. Everyone has their own style and characteristics, and choosing clothes that suit them can better show their personal charm.
