This pretty thong is by Woolworths.
It is labeled a size XL but I am calling it a size XXL.
The label also says "To Fit Hips 125 - 136 cm" which is about 49 to 53.5 inches.
See the measurements below to be assured a proper fit.

The waistband features a 2 inch wide strip of scalloped geometric patterned lace.
The body is sheer lace with a floral pattern.
The leg openings are trimmed with 1/2 inch wide lace.

Laying flat, the panties measure about 17 inches wide comfortably stretching to about 21 or a bit more inches.
The rise is about 9.5 inches.
