5 Vintage Bras by New Dimension by Miss Penny Rich UNWorn White mixed sizes

Description

Vintage "The Incomparable New Dimension Bra" by Miss Penny Rich...for Beauty, Comfort, and Health.  All are white and the same style (but different sizes) - never worn.  Sizes are 30C+, 30 D+, 36 C+, 34B, 30C.  Cup is 100% nylon.
Butterfly adornment.
Nylon and Spandex make up the rest.  The hooks are metal.  A pamphlet with directions will be included.  The following is part of the instructions:
To put on your Miss Penny Rich Bra, hook cups in place, and then put on the bra like any other garment.  Adjust your bra so bottom band lies flat against your body, under your breast (this is important).  Keep the back as low as normally comfortable.  Adjust shoulder straps, if necessary, pulling from front until bust straps are firm in place.
Unhook Cups.  Be sure each breast is centered in the center of the "triangle arch" as shown in Fig. 1.  Adjust Spanalift so it lies smooth on the bust.
With one hand holding Spanalift where it joins triangle bust straps, gently bring flesh forward from under arms to within the "triangle arch" around top of bust, as shown in Fig. 2. REPEAT THIS SEVERAL TIMES
Next, cup one hand under breast.  Gently bring flesh up and over top of Spanalift, as shown in Fig. 3.  DO THIS SEVERAL TIMES.
Since these are different sizes they probably won't fit ONE person, but would be great if you had a vintage shop and looking to resell.
