There is no one-size-fits-all swimsuit. However, a one-piece, two-piece, and bikini are designed to fit on more than one body type. While the tankini style looks good on different body types, you can also use a scoop neck top with swim bottoms. This style looks perfect on both skinny and chubby body types. Another viable option is the monokini, which is an ideal bathing suit for girls. The bottom line is to wear something that flatters your best features and makes you comfortable.
