See are you talking about US, UK, aussie size? Its just like
triumph bra and victoria secret bra, its different measurements and
a size small can vary. It would be best to state ie small for chest
size 80cm - 85 or 32 - 34 inch 
You might want to state like 100% fine silk... at least pple will
know they're paying for a quality product... etc small little
details entices the buyer...
If its your own branding, then I suggest you come up with a brand
name, it gives it a premium over the price, 'jus lingerie' or 'a
gentle touch' some name... otherwise, pp wun be able to recongize
it and label it MIC - made in china - PRC wear, I dunch
want...
