I am crazy about these hi-neck tanks !!! They are extremely flattering and look amazing dressed up with a blazar for the office or dressed down with a pair of ripped denim jeans.   The colour looks very pale in this photo however it is a lovely light, pastel blue.
The sizing is comfortable (a more generous fit)
95% Polyester/5% Spandex.
Machine Washable.
