I'm looking to create a private label line of seamless activewear and would love to see samples of scrunch leggings and matching sports bras. Could you please provide details on the fabric composition, including the nylon/spandex ratio? Additionally, I'm interested in knowing the MOQ for each style, the cost of samples, and any customization options available, including logo placement, labels, and packaging. Lastly, what is the typical production timeline? Thanks!
