Went to M&S today and bought some Girls' size (15-16 yrs) 底底. I'm surprised they fit even a little big. I'm 30" waist and these 底底 look as though they fit 31" perfectly and might even work for 32". They must be designed for westerners so the sizes run big. The design is conservative, but is a classic style for girls really...
You can go to M&S website and check the style, under School Uniform and Girl's Underw. They are available in-store in HK so don't have to buy from UK and pay shipping. Plus shopping in the kids clothing section would make you feel less embarrassing for sure
Hope you find this useful.
