"Hot Milk" nursing bras- anyone know how accurate their sizing is please?

[EachPeachPearMum]

Hi,
I want to get some new nursing bras for when DS arrives... having dug out the old ones, and actually looked at them

Does anyone know how accurate the sizing is- do they come up big/small.

(I find M&S come up big on back sizes... and Emma Jane came up small on cup sizes if this helps any comparison at all)

TIA

They come up big on back sizes, IMO. Seem pretty standard on cup sizes.

Thank you- very helpful! Am 32/34 but it makes such a difference if they're cut big!
