To ensure a smooth silhouette, opt for seamless underwear or shapewear that provides coverage without bulk. High-cut styles and thong options can also be effective in preventing lines. Additionally, consider wearing a slip or investing in dresses with built-in linings that offer extra coverage. With these tips you can enjoy the celebration without any wardrobe worries.
