Thank you for finding my item out of many others! This is a detachable collar made from silk fabric. It is a handmade item. ★ Perfect for those with sensitive skin, those who easily get itchy necklines from knitwear during the dry season, or those who find layering uncomfortable! ★ It also helps prevent bulkiness during the upcoming season. ★ As it's made of silk, it also functions as a neck warmer. ★ Easy to put on and take off as it's a slip-on type. ★ Four elastic bands create a lengthening effect for the neck. ★ Comes with a black grosgrain ribbon for a more dressy look (sewn on, not removable). The main body is made from genuine silk crepe de Chine. The lace is delicate antique-style cotton lace. The fabric is double-layered only in the elastic channel area. It's made using plain, off-white crepe de Chine fabric, so it will dress up a simple knit. The knit sweater in the image is for reference only and is not included. Size Current elastic finished dimensions: Top elastic finished dimension: approx. 38cm The elastic dimensions are finished longer in 2cm increments for each row, so it will fit the neckline. ★ There are elastic holes, so the size can be adjusted. Specifications Four strands of soft 4-cord elastic for softness. Height from the elastic channel to the frill: 7cm Single-layer part: approx. 9cm Ribbon length: approx. 130cm I have kept this at home without using it after purchase. Please consider this after understanding the above. #new #detachable collar #ribbon #genuine silk #silk #high neck
