Our Breast Sizing System is also available with two pairs of Purlz Breast Sizers. As with our triple system, our double system includes a sports bra in your choice of color and size, a pair of Purlz straps, and fabric tape to attach the sizers to the bra for more secure placement.

Many women do not find the tape necessary to hold the sizers in place, but we include it just in case your garment and/or your activity requires it. You may also find the tape useful if you try wearing the Purlz sizers with a different bra.

When you make your size decisions, please keep in mind the following considerations:

1. For sizers 200cc's to 350cc's many women find that a difference of 25cc's is perceptible. It may be useful to order your sizes in 25cc increments, such as 275cc's, and 300cc's. For sizers larger than 350cc's, it would be better to try 50cc increments, such as 375cc's and 425cc's.

2. We also recommend that our customers order one size larger bra with sizers bigger than 300cc's, especially if you would normally wear a size Small bra. Please consult our Implant and Bra Size Chart to determine a good combination of Breast Sizer and Bra sizes to order.
