Panties size

Because the Korean population has a relatively homogeneous body-type, you can find a lot of 'Free Size' or 'One Size' which is the Korean equivalent of 'One size fits all'. For bras, sometime there is no cup size, you will have to pick between 70, 75, 80, 85 or 90. If there is no cup size, it means that the bra fits cup A to C. So if you are a US 34A, 34B or 34C you can pick the size 75. In year 2020, there are more big sizes fit up to cup D. 

For lingerie sets, you will have to pick the size for the panties. You can find 3 types of sizes on Somethin' Sweet:

  • • Free size: This is one size fits all and fits from XS to M in international size. The size option will be written as 75/F (F stands for Free size for the panties, not F cup).
  • • S / M / L size: This is the international standard size.
  • • 90 / 95 / 100: This is respectively XS, S and M size. 
  • • Unfortunately Korean brands do no offer a lot of plus size yet. On Sthsweet only Justone and Chuu will offer plus-size lingerie
