Silky, colorful midi-length dresses, size 18

[Antst]

I'm no fashionista, but love cosplay and dressing up for special events. Last weekend I went to London and saw two or three women wearing outfits that look great for an event I'm going to attend.

They had black legs (tights and boots) and silky midi-length dresses in muted, but bright colours. The dresses didn't have that "nightie" look that's common in the plus-sized world and is quite unflattering on me.
They were gently structured. One was a robin's egg blue print.

Unfortunately, I have no idea where to start as far as finding anything similar. I recently lost weight and now wear a size 18. I know what's available in the plus-size world and there's nothing at all like what I want. But I can fit regular sizes now and hope that someone might know what I'm talking about and can point me in the right direction! I had the impression that this is a look that will become popular, so maybe it's in a store somewhere! Thanks very much.

Thank you very much. The blog is helpful. She seems to like the same basic shapes that flatter me.

It's weird that although there are now more styles available in stores that flatter everyone (I particularly love that midi lengths are easy to get and affordable instead of only available at LK Bennett), the shapes can be a problem. I went shopping for jerseys/sweaters a few weeks ago and everything was cropped (I'm tall). I've had a hard time figuring out how to adapt. So it's nice to get inspiration from other women who aren't 20 anymore! Thanks.
