My best friend asks you if she looks good in this dress, and how to express her high emotional intelligence?

Depends on how you and your intimate relationship are going. If you are really close, you two are generally teasing each other, so don't worry so much about your words.

You only need to express your opinion, and you can also express your meaning in humorous words. You tell your best friend that you don't deserve the charm of this skirt, so change it! Your best friend knows that she won't look good in this. Try to wear this skirt as little as possible in the future, or maybe she will return it for another style.

If your girlfriend is a sensitive person, she will care about everything you say. Although your intimate relationship is unusual, she will still be unhappy because of a sentence or two.

Just try to express yourself politely. You can say that this skirt doesn't match her noble temperament. You can give her some advice on what kind of skirt she is suitable for. Your best friend knows that this dress can't highlight her beauty, and she is willing to change it.

Of course, you can also point out what's wrong with your girlfriend's skirt, what aspects can't highlight your intimate figure and so on. For example, you can say that if you wear this skirt, she is slim, which will make your intimacy look fatter.

Or maybe your best friend wears this skirt with a small waist and can't stand out from the waist, then your best friend will find that this skirt has many shortcomings, and she won't choose this skirt again.
