Do you hate your bra ? Here's why.

Every single day I read women complaining on their bras. Are there any objective reasons to this mass hysteria ?

Step into a modern lingerie boutique.

All bras look the same. Is it because all boobs look the same or all boobs look the same because all bras look the same ?

Quite a chicken or egg first problem indeed.

Except that this one has an easy solution. It's all about cheap cash.

Will you put your boobs there ? I'm sure you'll think twice indeed.

Most cup sizes and all shapes come from the same process: Temperature enhanced press molding.

Don't get e wrong, molding can, with appropriate materials and techniques, produce amazing complex shapes.

Luxury that mass-production undergarment industry can not afford.

Therefore most bra molding machines assume that boobs are spheres.

Which kind of works because breast tissue is soft enough to occupy spherical containers given enough pressure.

EDIT:
Here was embedded a video of sheer cups bra press-forming process. Which disappeared from YouTube shortly after this post went online.

Most sheer cups and finished bras are also press molded. Way cheaper that sewing precisely cut panels.

Yeah, but why should this be as bad ?

From structural engineering point of view, boobs are not spheres. They need support and not compression.

Second interesting property, thermal molding does not preserve material thickness. Nope.

The portions with major extrusion will be thinner than the ones with less shape change.

Which in this particular process leads to the outwards portion becoming thinner with less elastic reserve than the base. Quite the opposite of what nipples like BTW.

So yes, the answer is now clear, all boobs look the same because all bras come from the same presses.

Further on the topic. Press molding involves high temperatures. Material needs to pass from elastic domain to plastic deformation in order to preserve the form.

I'm not a chemistry guru however I know that most plastics and synthetics will undergo permanent chemical changes when subjected to higher, in the realm of 200C, temperatures.

Reason why all food related plastics are specifically formulated to remain chemically neutral when molded / shaped / extruded under stringent temperature and process control conditions.

That cute lace fabric might look awesomely appealing and be perfectly suitable for contact with delicate skin. However once heated to it's melting point, it might degrade and start oozing components you better don't ask about.

Quite a bunch of reasons you might hate your uniformizing and probably even toxic bra.

Time ago bras and corsetry were structural items made of purposely shaped stitched together patches.

Vintage lace cups structured bra.
Structural engineering at it's finest.
Structural engineering like in bridges or aircraft. And it worked big time indeed.

Think of it next time you buy a bra. Although harder to find, structured models do exist and wearing them is quite a departure from the uniformity of press-formed motorcycle helmet liners.

Just dare to try.

I love you, I love you all !
