Even with nude invisible panties, you will be able to see the outline no matter what. I tried buying a liner but since the dress is fitted at the bottom, it folded inside. I ended up having to spend another 60$ on nude spanks that went up to the bra just to make this dress work. The material feels cheap as well but I had ordered it last minute since I needed a dress for my engagement party. I would not recommend. The dress fit well.
