Does black dye make material stiff?
I was a little worried ordering the black Bra as I have noticed they sometimes will fit smaller than a Beige or white color will fit. Strange but true!  I went ahead and ordered anyway because no comments mentioned anything about the Black Bra being any different than the other colors.

***Please note that on this Black Bra I am hooking on the loosest setting, while on the Beige Bras I hook on the next to tightest setting. ***This is a 1 1/2 of an inch difference*** But for me it does still fit and it looks good too.

The Black material seems thicker and more stiff.

The straps do give me plenty of adjustment room. (some bras I have tried have had such a shortage of material in the straps I practically get rotator cuff trauma trying to get them on!)

I do really like this style of Bra: The cups are soft and seamless, and the sides are nice and wide (concealing excess boobage) without cutting into my under arm, and I do like how this style has padded straps and 4 rows of hooks instead of the usual 3. It is supportive and comfortable and I am so glad it doesn't have underwires! A good purchase!

UPDATE 11/24/13  The Black Bra is still holding up very well compared to the Beige Bra.  The beige bra is all stretched out looking in the band area.  So perhaps having a more tight and stiff material with the Black Bra is an advantage!  I am glad I bought the Black and will not hesitate to buy again!
