I have bought this dress but it's not very forgiving and the opaque tights I tried it on with had a seam down the front which could be seen through the dress. So, I think I need opaque tights without any seams, if such a thing exists, and that could possibly also be worn without pants (although I'm not very sure about this). Does anyone have any recommendations before I spend a small fortune trying various things that will be no good? Thank you.
