This site has nice bikinis for girls that have large chests. Although they say they offer bathing suits up to size 4X, that proved difficult to find. In fact, many of the bikinis only go up to a 14, and the largest we saw was a 20. We would recommend this site more to girls with a big bust who aren’t necessarily truly plus size because the tops do go up to about an F or G. This site is owned by Fantasia wear, which is featured in the bras and lingerie listings.
