How to buy the right size undies when you are pregnant?

Congratulations on your pregnancy, I do hope you are feeling well! I like pregnancy, well apart from the nausea and chronic reflux, but thankfully the nausea subsides and the reflux can be treated.

I gained about 10-12kg during my pregnancies, and this extra weight gain meant I required some bigger underpants. I thought it would be useful to provide a guide on how to buy the right underpants size based on kilograms gained.

The average woman gains 1 to 2 kg in the first three months, followed by 1 to 2 kg per month during the final six months (www.thewomens.org.au/Weightgaininpregnancy).

Based on these averages, after 16 weeks you may have gained approximately 2 to 5kg, which is equivalent to one half to a full size. Not all women will feel the need to purchase a larger size at this point. After 32 weeks, you may have gained approximately 5 to 10kg, which is equivalent to 1 to 2 sizes.

Most women know their bodies and will have a good idea of how much weight they are gaining. I recommend my customers and pregnant friends purchase a couple of pairs of underpants 1 size bigger at the beginning of their pregnancy and then a few more pairs at about 5-6 months, 1 to 2 sizes bigger. I would also suggest buying Hipster styles so the underwear can sit comfortably under your baby bump.

In terms of how many pairs to buy, I would say enough to see you through this and future pregnancies, but not too many as to stop the incentive of losing that extra baby weight.

Good luck ladies!

  • Given we do go up a size or two during pregnancy it would be good if the maternity briefs were available in bigger sizes. Right now they only go to size 18, so if you started larger than a 14 you might not be able to reap the benefits of Modibodi, right when you need it most!
