Your first bra fitting

Having a bra fitting as a teen hits the top of the 'most embarrassing experiences' list. It's different at Brava. Yes, we do check the fitting but the rest we leave to you as we know that standing half-naked in front of a stranger is your worst nightmare. We will not force the dreaded granny bra on you either - we promise.

First Bra Fitting Guide: How To Choose & Which To Buy

Fit is foremost but we don't compromise on fashion for fit, we can give you both. Also, remember Brava was born because the owners had horrible bra fitting experiences as teens ... and all Brava fitters are D cup & up too. We get it!

We know that most teen girls...prefer moulded bras, don't like sheer materials, prefer thin straps, they want bras similar to those worn by their smaller breasted friends and they certainly don't want bras that their mothers or grandmothers like to wear.

50% of teen girls visiting Brava do like to have help from their mum... BUT the others dread it, and sometimes it works best if mum hands the job over to Brava fitters who are adept at maintaining communication while minimising embarrassment.

We hope you feel fully prepared now for the first bra fitting experience! For any questions you have, please email our Brava Bra Experts anytime.

Breast development in teenage girls


Breasts go through many stages of growth over a period of five to six years. Development normally begins about 1 year before the menstrual period begins and full maturity is usually reached by age 17 or 18. This generally happens around 4 years after the start of menstruation, but not always. Breast development during puberty is still not considered mature or fully-developed, because only pregnancy brings about fullness of breast growth and development.

The Shape

The breast is made up of milk glands and ducts, connective tissue and fat. In teenagers the breast tissue is firm and dense and then becomes softer and more fatty with age. Because there is no muscle tissue in the breast there are no exercises to make you bigger or firmer. The pectoral muscles that lie underneath the breasts can be firmed up to provide lift and shape.

Stretch marks

Hormonal changes that occur during puberty can trigger a rapid growth of breast tissue. As the breast tissue increases, the skin stretches. The thinning of the skin can lead to stretch marks on the breasts. Stretch marks are a normal part of puberty for many girls. Your breasts can feel tender and itchy as they are growing and stretch marks may appear but they will probably fade.

Breast size

Because your breasts contain fat cells your bra size may increase with weight gain. Breast size is primarily determined by genetics. It can be complex in that your genes may come from your mother or father’s side, or even from distant relatives. Many girls will have a breast size that is very different from their mother's or sisters' size.
