My lingerie size 

Determining the right lingerie size

To determine the right lingerie size, two girth measurements are needed: the girth under the bust and the bust size. The size table can be used to determine the correct lingerie size.

Step 1: Measure the girth under the bust (ribcage) to determine the circumference size

Step 2: Measure the girth across the bust (fullest point) to determine the cup size

Cup size is too large

First check to make sure the torsolette is pulled downwards enough at the back, so that the cups fit properly on the front. The cup must fit closely around the bottom of the bust (ribcage). If there are folds in the cups or if the breasts hang too low in the cups, the cup is too large. In this case, use the push-up cups or a smaller cup size with the same ribcage size.

Cup size is too small

If the underwire supports are too far from the body and/or pressed under the arms, the cups are too small. In this case, use a larger cup with the same ribcage size.

Cup size is good, but ribcage size is not

In this case, use a different girth size as well as a different cup. If the girth becomes larger/smaller, the cup will also become larger/smaller! For example: The cup fits right with size 85C, but the girth is too small. Try a 90B (not a 90C), since a 90B has the same cup as an 85C, but a larger girth.                                                                                                                         

The lingerie size does not exist

Poirier lingerie is available in sizes 70A to 110F. It is possible, however, that the size needed falls outside of this range or that a particular model in the size needed does not exist.

Possible solutions:

  • Use fasteners (hook and eye strap) as an insert to increase the girth (ribcage). 

For example: 100A = 95B + hook and eye strap.

  • Determine an alternative size. For example: use an 85G for 80G.
  • Use push-up cups if the girth is good, but the cup is too large.

For example: 90A = 90B + push-up cup.
