Q&A on bras
Do we need to wear a bra?
Statistics show that 7 out of 10 women don't know their actual bra size, and this leads us to wear models that don't fit our breasts. Wearing a bra isn't physically essential, nor does it improve our health. However, due to upright posture and the weight of our breasts, breasts tend to sag, and a properly fitted bra can improve our aesthetics and self-esteem. Dr. Elisa Fernández emphasizes that the key is choosing the right size: both the band and the cup. As for underwires, they aren't dangerous if they fit properly; otherwise, they can cause minor discomfort in the breast.
How large should the straps be?
Dr. Fernández does not hesitate about this one: “the bigger the breasts, the larger the straps!”
Why does a conventional bra size have a number and a letter?
Regular bras have a double numbering or code, consisting of a number and a letter. We usually simplify by saying we're a size 90 or a 95. To know which bra is ideal for us, we'll also need to know the cup size, that is, the breast volume, which is represented by the letters A, B, C, D, E, and F. So, our bra size will be 90A, 90B, 90C, and so on.
How is the size of a conventional bra calculated?
- 13 cm = Cup A
- 15 cm = Cup B
- 17 cm = Cup C
- 19 cm = Cup D
- 21 cm = Cup E
So, if you have an 80 cm underbust circumference and a 95 cm bust circumference, the difference is 15 cm → Cup B.

Is there a match between the Nightbra size and the daytime bra size?
What is the underbust circumference?
It's your circumference, measured just below your bust. Determine this measurement in cm and find the result in the table below to find your Nightbra size.
What is the ideal bra?
Dr. Elisa Fernández tells us: "I don't think there is an ideal bra. Every woman has a different body type, and each woman's breasts are different (sometimes by more than one size). In reality, the ideal bra should be custom-made for each woman."
Why does Nightbra, the anti-wrinkle bra, have no cups?
The lack of cups is due to the fact that at night you should never sleep in a conventional bra or one with cups, as this does not facilitate lymphatic drainage and encourages the formation of cellulite in the armpit area. Therefore, since we wear a conventional bra for twelve hours, which compresses the breast and the breast tail (the end of the armpit), we can allow lymphatic drainage from the breast to the armpit at night thanks to a cupless bra. Furthermore, from an aesthetic point of view, we will avoid cellulite in the armpit area. And we will also eliminate wrinkles on our neckline.
Why shouldn't you apply pressure to the lymphatic system at night with bras with cups?
Lymph is a fluid that runs through the lymphatic system parallel to the arterial and venous systems (it contains the lymph nodes). It's not advisable to maintain continuous pressure on the lymphatic area.
From a medical-aesthetic perspective, sustained pressure on certain areas of the body and lack of exercise lead to cellulite, which often accumulates in the breasts and even under them, as these are areas that aren't exercised in daily life.
The breast doesn't have muscles, but anatomically, it's located above the pectorals (major and minor). By correcting the posture of the back (with a nightbra), we unwittingly maintain tension in the pectorals, which makes the breasts firmer and counteracts gravity.
For all these reasons, we recommend that you do not sleep in a conventional bra (especially one with an underwire). Your breasts should be free at night, as they need to rest from the pressure exerted by the bra during the day and allow your lymphatic system to do its job.
