Off-white long-sleeved blouse - Color: Off-white - Sleeve style: Long sleeve - Neck style: Round neck with a slight V-neck - Hem style: Elasticated - Back style: Buttoned - Material: Lyocell (cotton lining) Thank you for viewing. I purchased this about 5 years ago and have worn it a few times. The outer material is lyocell, which gives a gentle impression even in a business setting. The cotton lining prevents transparency. The elasticated waist allows you to wear it with a suit without needing to tuck it into your bottoms. Although it's a size M, the neckline is quite open, so please be aware if you are concerned about showing too much décolletage.
