Constructing the Basic Bodice Block
Added Feb 22, 2009
This is an odd looking measurement. We are going to measure from the point C towards the point B, a distance of one half the CHEST measurement plus one half the DART size, and mark the resulting point (point T). These two measurements require some explanation. The DART size is not actually a measurement, but it is scaled with the bust size and hence is treated in a way similar to the measurement estimates already presented. The CHEST measurement is the width of the chest at the front of the body, above the bust but under the arms. However, the CHEST may also be computed from the BUST measurement. Nonetheless, the CHEST measurement may vary quite a lot from the estimate - it is advisable to measure this separately.
Here are the calculations for the CHEST measurement if an estimate is used : add or subtract 1.2 cm to 32.4 cm for each 4 cm bust increment above or below 88 cm if you are using metric measurements ; add or subtract 1/4" to 12-1/4" for each 2" bust increment above or below 34" in Imperial units. Also, here are the DART calculations, which you will need as this cannot be measured directly : add or subtract 0.6 cm to 7 cm for each 4 cm bust increment above or below 88 cm in the metric system; add or subtract 1/4" to 2-1/2" for each 2" bust increment above or below 34" in the Imperial system. Make a note of the DART width as calculated here. Draw a vertical line up from point T to just below the level of the line HI.
