I ended up buying two pairs of these to go with my black lace bralettes from obc - I love the way the band adds colour to the design without overpowering the black lace. Taking off one star because I think the lace panels could be a little bit bigger - it’s hard to see the lace from the front or back for those with wider hips! But the design is a good basic.
The material is standard for obc - very smooth. I’m in between sizes for the waistband but the leg holes of the S/M for this cut fit me best (I prefer a slightly snug fit), so I’ve been stretching out the waistband of the S/M after each wash. 2-3 rounds of stretching the waistband over a wide chunky plastic hanger and the S/M fits well.
On a more general note, suggest that obc offers a size chart that gives a more accurate picture of what the waistband and leg holes are like for different underwear designs. The current one gives the impression that all the undies have the same cut and level of stretch, but in reality the stretchiness of the waistband and leg holes (and therefore the comfort of each size in each design) varies quite a bit depending on the material and lace for those of us who are between sizes, especially if we’re larger.
