Cheshire - I just bought a wireless bra from M&S as there was a sale n i've become a little bigger. Got a rather comfy one at $30 (original price was $59). I previously bought a nursing bra from there as well n it was ex as there wasn't a sale ($79) but comfy too! Decided on a wireless normal bra this time as the SA at Mothercare advised that size would change again at about 7 mths. After delivery, there would be engorgement too so I only bought one now to tide me over before investing in the bigger sizes for future. For those, will get nursing bras.
