Dear Ching , As I advised you that we recently are unable to find the thinner and softer elastic to folding 1 cm at the top of waistband , so we only submitted 2 options ( mock-ups) to you review . The folding elastic must be special weaved based on WB height and we are re-checking with other suppliers if they have available folding elastic that can use for LFM sample first and will update you the checking result on next Monday . According to 2020 calendar , the latest LFM sample ex factory is Jan 3rd , pls do confirm it is correct and can allow more few days to send this style by the week of Jan 7th ? we are considering to weave the elastic if still can’t find any suitable elastic q’lty ( folding type ) fm market . pls check and advise . thank you . Gina
