There are even more corset pattern shapes to choose from than lengths (on hips, over hips etc, see last few posts for more details). Below are examples of the main ones; the top line shows those commonly used for corset training, the second row are the more exotic but also more problematic corset styles that I don’t recommend for waist training, they’re included for educational purposes.
The waist cincher has been covered in the previous posts – this is the same as a ‘waspie’ or short underbust and is for active wear. The two main types you’ll have to choose between are the hour glass and the conical shape.
The hour glass corset pattern is named after – you guessed it – the hour glass, the ones filled with sand, as it’s wide at both the top and bottom but goes in dramatically in the middle. The important thing to note here is that this pattern allows for the ribs, you should have little or no trouble taking full lung-fulls of air while waist training in this style. The conical corset however, squashes the ribs which are forced into an upside-down cone shape that tapers down to the waist. This style will restrict lung capacity and over time corset training with a conical corset is said to change the shape of the ribs permanently. A lot of tight-lacers consider this the proper corseted body shape.
