These are the H.B.T. (herringbone twill) trousers specially design for women in WW2.  

This was the summer field uniform worn by women in the US Army including the Nurse's, the M43 combat jacket or the Officers field coat could be worn over the HBT uniform in colder conditions.  

Theses are the same correct fabric and design as the previous runs but we have improved the sizing of this 2020 production. After customer feedback we have made some changes to the sizing, in particular we have have made the waist slightly smaller and the hips larger which gives a better fit than the previous trousers we have also made the leg lengths shorter in particular the smaller sizes.

These changes were due to customer feedback so thank you for getting in touch and helping us to improve.
