I have the larken x in two colors and what I love: the fabric is so comfortable, no bunched up back rolls, easy to breastfeed or pump in, low profile without clips.
What could be improved: I wish it was a bit longer so I could truly wear it as a slightly cropped shirt, right now I could only wear as a crop with super high waisted leggings. My torso is average length and it hits ~3 inches above my natural waist. And I wish it felt more supportive and/or the fabric was thicker. I wouldn't wear it to workout/hike, and probably wouldn't wear it out and about unless I'm in a very loose shirt because nipples will for sure show. I would LOVE if they came out with a version more gear toward working out/being active.
