No. The breastpumps fit in most bras. Choose a bra made of a stretchy material. The collection cups will usually fit into a breastfeeding bra better than into a normal bra. However, some women who are breastfeeding find that a bustier is better than a bra.
Make sure that the Ardo Melia doesn't sit too tightly in your bra, as this could impair expressing. If the pump is pressing too hard against your breast, loosen your bra straps. And if necessary, use the strap extensions provided to adjust your nursing bra.
