Why research our average cup size?

As a lingerie manufacturer I would want to know about sizes. It will give me insights of what sizes are best sold and what sizes I might focus on in the near future.

A research brings a question like ‘how come the average bra size has jumped from a 34B to a 34DD in 20 years time’? We learn that weight gain and breast implants played a role in the increase.

Researches give us the possibility to compare. Well, we are kind of forced to aren’t we? Being brought DD right into our face (as would any outcome of cup size).


How petites are missed in the researches

One of the researches is based on 60,000 customers that were interviewed at 16 stores nationwide.

Tell you one thing about petite cup-sized women.

They never visit a lingerie store.

Having an AA or AAA cup we feel like we don’t belong there (which indeed we do not).

99% of the lingerie stores do not sell our cup size. Chanches are you were advised a too big cup.

 do researchers even know the existence of the smallest cup size?
probably not
many petites do not even know their true bra size

The focus on boobs getting bigger is surely there. And maybe it is the case.

In my opinion we petites could fill up a whole new planet. Many women have them. Little boobs. There always will be ☺
