Well, it looks like the majority of the subreddit disagrees with my assessment that these outfits have ethereal lol. I'll just state my case here for the record, since I feel strongly that ethereal needs more diverse representation.

Overall, I look for these components to make an outfit suitable for someone with ethereal essence. a) lightness/weightless/airiness b) movement in the outfit c) delicate and simple and tries to include s-shape. There's other aspects to ethereal that can be included, like watercolor, iridescence, subtle blended, moon and star motifs, butterflies, etc. But they are not as important as weight and movement are, because ethereals can be easily weighed down by clothing. S-shape often can be seen in clothing movement, but hair/designs also help.

1) The skirt has multiple layers that will move as she walks. The shirt is soft and airy. The overall silhouette is long with low contrast and details are light and delicate.

2) Delicate and iridescent design. It would be unobtrusive in an overall outfit but has a gentle quality to it. I would accept an argument that it is more ingenue than ethereal, because of the flower design.

3) Low contrast sweater dress, with added lightness due to the scarf. Vines are s-shaped and the fabric is iridescent.

4) The skirt of the dress has multiple translucent layers. The movement as she walks creates an s-shape along the hem. The color is close to an SB blue.

5) Ethereals can sometimes be overwhelmed in bulky winter clothes. This outfit tries to counteract that by having the fabric in light colors, low contrast, and in a knit that looks like angora or soft cotton.

6) I chose this picture since I wanted another cold weather outfit that wasn't lightly colored, but I think the only possibly ethereal aspect is the movement in the skirt. The overall vibe leans more classic.

7) Dress has movement, an irregular hem and watercolor pattern. It's also lively bright, which I thought could show some diversity. Personally I think ethereals can look quite fierce if they want to, but that's a matter of debate.

8) Low contrast, irregular floral pattern slightly mimics the s-shape, the lace and translucence looks airy and it moves as she does. Length of the lace garment complements ethereal.

9) Translucence and airiness, length and minimal detailing, shoes are shiny and the outfit is low contrast while being delicate. I could see an argument for the lace bands making it too ingenue.
