Do I need another bra size after breastfeeding?

Women tell me they have lost breast tissue after having their child or children. When I go through their sizes with them, they usually need a new bra size.

A new bra size might mean a totally different size. But it might mean a different band and keeping the same cup volume.

A bad-fitted bra is with you all day. This kind of bra is not giving you a good feeling, not at all. If you’re not happy with your bra, or maybe never have been anyway, it is surely time to measure your bra sizes.

This seems the logical thing to do. But in reality, women may stick way too long with their bad-fitted bras (which happened to me).

Having a child and breastfeeding your child can have an impact on your breast tissue. You may also find your boobs sag (even) more than before.


Why we don’t take action (it’s so human)

  • we somehow stick to a cup size we are used to (even if it no longer fits us)
  • although we need only about 10 minutes of our time to check up on our sizes, it’s not on our priority list, especially with a young child around
  • women with small breasts need to look at a bra size chart that includes all small sizes (or you will just miss your size and go for something that’s close but not right for you!)

Having smaller breasts after breastfeeding is very common. If this is the case you cannot possibly be wearing the same bra size that you were used to.


How to measure my breasts?

Measuring your bra sizes is something every woman should do. For some, because of body changes, it would have to be a regular thing to do.

Of course, you can ask someone else to help you measure your sizes.

Are you small-breasted? Check your size in Small Size Chart

The common bra size charts usually start from cup A. If you are small-breasted be sure to check a bra size chart including AAA, AA, and A cups. Maybe your underbust size has changed and so have your boobs. This could, for example, mean you would go from 38A to 40AA or 40AAA.


Which bras should I look for?

Once you know your best bra size you could wear anything you like. If you wear the right bra size any style of bra can be good for you. It’s personal of course. But wearing the right bra size will make all the difference in the world.

Just one more thing about sizing you need to know.

It could be you would fit 2 bra sizes.

When you are just in between two measurements you could actually fit different sizes. Try both sizes if needed.
I wear bras in 34AA, but I also wear 36AAA (the cup size is the same but the band is a bit wider). I even have some 34A depending on the model and brand.
