Am I the last to know that bras in black and darker colours tend to run smaller, due to the dyeing process? 
If not, then why didn't you tell me? 
All these years of having boobs and wearing bras but I only just found this out yesterday!  |

"To be honest I’m not even sure what your post means? Darker coloured bras run smaller? "
If the bra is black or navy blue say, its likely to be a smaller size as opposed to a white or pink bra which will be a larger size due to the lighter coloured fabric requiring less dye. |

Ah right, gotcha, thank you 
I never knew this either. So in theory then the BBWs should mostly be in white / lighter bras on here then? Is that the case?

Ah have I misunderstood then?
Does it mean that a 32c black bra will be smaller than a 32c white bra? I’m confused now…
I thought they meant that the range of sizes available for darker bras is more limited than the range of sizes available for lighter bras.
I’m just a simple country boy. I get confused very easily!! |

"It's the same with all dark dyed fabrics. Darker the dye, the less "give" in the fabric. Bra, denim or shirt, all would tend to run "small" in darker sizes."
Thank you!!! You explained it better than me |

well I've learned something new today and I thought you couldn't teach an old bitch new tricks??? hahaha
I've never ordered a different size depending on the colour before,
ever,
they all seem comfy and supportive
apart from the ones with wires which I avoid like the plague anyways coz they dig me in the arm pits every single time.
Guess I've been lucky then that the black and dark blue or dark purple etc actually fit me.
The one I fall out of most happens to be white, actually, but it's a vintage cross yer heart torpedo cups style jobby built more for style effect than comfort
I would love not to have to wear any but I can;t go bra-less, the effects would be  |

Why should they be?  Bras come in cups up to M now. As well as wider bands. |

" are you serious OP? That would actually explain a lot 
K"
Yep! There was a style I tried on in a blue, green and black. The assistant mentioned the dye thing and lo and behold, I needed a wider band for the black.
Unsure why I never even realised this myself, without being told  |

Another good explanation. Thank you. Now I'm remembering a pair of jeans I had in black and blue. Wondered why the black was tighter at the time |

Me too. I was never great at physics though and not much has changed there. So have just accepted this fact and now feel armed with the knowledge |

I hate to burst bubbles but it's only partially true. The only dyeing process that will cause this is vat dyeing. Vat dyes are only used for cotton or linen and the caustic used in the process will cause pre-shrinkage so you will see less "give" in the fabric. Therefore you'll only see the effect in cotton bras (and as you rightly say black jeans). The materials used typically to make bras will use different dyes and processes which don't cause preshrinkage.

I was thinking that this shrinkage would only be an issue if the garment is dyed after it is sewn. If the fabric is dyed and then the pieces cut for each size, the amount of material is equal in comparison but the amount of stretch/flex would be different. |

I didn’t understand the original statement at first, I interpreted it as they only make bras in a smaller size range rather than that it ‘shrinks’ the material, hence my comment. I’ve now been re-educated! |

"Surely, if they can make a pen that writes in space and food that can finish cooking in the microwave, they can work out the % shrinkage from dyeing and make them that much larger before dyeing?

Well I have to admit I thought this too! Surely they dye the raw materials FIRST, and THEN cut it to the correct size they want (after the shrinking process has been completed),
Not, as is implied, make it as a generic white bra and THEN dye it so it shrinks from its original size? That seems back to front!

Agree with earlier comments about vat dyeing. Jeans DO come in slight variations because they are made then dyed, and dyeing process on thread count (causticity, agitation levels, rinse cycles) locks threads and "shrinks" jeans at first till worn.
Bras - you *could* do in same way but they have so many material mixes in one product very unlikely, and would fall apart if post construction vat dyed (unless denim bra!)
Another issue is country of origin for consumption. Each country historically produced against models based on female form in own country. A bra or dress made for an 'Italian' woman of 10/34b wouldnt necessarily fit 'English' woman of same index.
Of course could just be bras are badly made to make women go up a cup size rather than strap size for ego boost. USA shifted entire dress sizes for that reason |

It can be true that darker dyes cause more shrinkage but the fabrics are dyed before the bras are made. It can make the elastics a bit firmer but the tension of the elastic when stitched to the bra tends to be electronically controlled these days. |

I didn’t know that, thanks. That will be why M&S don’t sell my size in anything darker than blue |

Thanks for this further insight
I guess that the synthetic band part of bras and whether you fall at the top or bottom end of your band/which hooks you use also makes a difference to the fit? |

Ann Summers . Unplanned trip, as just happened to be walking past on my way back from an appointment. One of my favourite bras "died". So I went in and tried on a style in three different colours and was told the info.
As others have said re varying sizes depending on the bra, style and brand - I do (of course) have these but my initial comment was based on trying on the exact same style in different colours.

Sorry, this is nonsense. Clothing, including bras, is made after the material is dyed. What makes you think they are made and then dyed? |

Not necessarily true...some clothing is garment dyed...but not usually bras. |

Do they dye the material after cutting it then?

The multiple hooks are to extend the life of your bra so you can tighten it as the elastic stretches out. If you're using the tightest hooks when you first buy it, it's too big. |
