Thank you for bringing this to our attention, we are looking into this fit issue. At Dreamgirl we take pride in making all woman, of all sizes feel both sexy and beautiful. This style is a One Size Fits Most sizing, we always strive to have these styles fit most woman, we apologize for this inconvenience. At the moment we are not changing the sizing on this style, but in the future we will consider making thongs in additional sizes, not just the O/S.
