Walmart offers the Suddenly Slim By Catalina Women's Slimming Shirred Halter One-Piece Swimsuit in 23 colors (Serrano Pepper pictured) for $25. Opt for in-store pickup to dodge the $4.97 shipping charge. That's $10 off list and the lowest price we could find. It's available in sizes S to XL, although not in all size/color combinations.
