These are the ones I buy, by the same company funnily enough. They have a thicker strap than yours. The only seam is a tiny one at the top of the cup area where you can remove the pad. These things are my favorite and they were a life changer for me.

ETA: they have no underwire but provide enough support that I’m not jiggling around. The pad prevents headlights and overall the bra provides me with a nice professional looking shape. I got several of them for my mother, too, since I love them so much and she also adores them. She’s significantly larger than me but still finds they give enough support and an acceptable silhouette.
