Recently while purchasing bras at Nordstrom, the sales lady mentioned not to squish the bra cups while washing or packing them for travel. I have always squishes one cup into the other to pack into a small bag for my tiny carry-on. But now I am rethinking my strategy. I have tried packing socks inside the cups, but it just ends up taking too much space and gets squished anyways among all my other stuff. Do you guys have any ideas for packing bras without damaging the structure of the cups? Are there any packing devices I can use for this purpose? Thanks in advance!
