To hide a lower belly pooch in a wedding dress, there are several options that can help create a smoother silhouette. Firstly, choosing the right undergarments can make a significant difference. Look for high-waisted shaping underwear or control garments that offer support and hold in any problem areas. Additionally, selecting an empire waist or A-line style wedding dress can help camouflage the lower belly region by drawing attention to other areas of your body. Another option is to consider adding ruching or draping around the midsection of the dress, as this detail can effectively minimize any bulges and provide an overall flattering look.
