Our Cuts

Over the years, we’ve developed a range of jeans and other pants to suit different body shapes and to work with your individual choice of style. We started with our original ‘signature’ straight cut, and now include bootcut, slim, super-slim and tapered silhouettes. None of our cuts is extreme, but rather we have developed a classic range of great-looking jeans and pants, beautifully constructed from superb Japanese denim and other fabrics.


This includes any jean with the 634 model number, which is where it all started for Iron Heart, so we consider the 634 to be our ‘signature’ cut. Loosely based on a 1966 Levi’s 501, it is a straight cut jean with a medium rise and slight taper from knee to hem. Other straight cuts include our 1955 jeans, loosely based on a 1955 Levi’s 501 cut with a higher rise and a fuller top block than the 634, and a selection of chinos and work pants.

Our slim cuts include any jean with the 666 model number, a slim straight cut jean, a little slimmer all the way through the profile than the 634, but with a similar rise. We call the 666 a ‘grown up slim cut’. Also included are our 777 jeans which are slightly more tapered than the 666 cut (the 777 cut is also included under tapered cuts) and our slim cut 721 model chinos.

Super Slim

Includes any jean with 555 in the model number. These jeans are a high rise slim jean. They have a higher rise than the 634 and are quite a lot slimmer all the way through the profile. They look great on larger people who want a slim look below the knee.

Any jean with 777 or 888 in the model number. The 777 cut is also referred to as a “slim tapered” jean cut, similar to the 666 cut but slightly more tapered. The 888 is a slim cut jean with a higher rise and more taper from the knee to the cuff, giving a very flattering, modern, slim silhouette. The 888 cut looks great on most body types and also women/girls. Other tapered pants include our slim tapered 721 model chinos and relaxed tapered cargo pants, the IHDR-502.

Boot Cut

Includes any jean with 461 or 463 in the model number. Our boot cut has a relatively low rise and a relatively small hem/flare. We create the gentle boot cut shape by tapering in at the knee rather than flaring out at the hem. This jean style is very slim through the thigh/knee and won’t work for everyone – but is an extremely flattering cut and fit when it does.
