Oh TrendyNannie6 I've been on the hunt for one of these for ages and still haven't managed to find a comfortable one! All the ones with bands underneath just seem to roll up uncomfortably underneath my boobs. It seems that you either have wires or bands, neither of which is comfortable. I went into Debenhams a while ago with the intention of being measured properly and hopefully getting some advice, but bottled it as I couldn't find a friendly looking assistant! I'm currently sitting here bra less after slinging it off after this mornings dog walk! I read somewhere it doesn't make your boobs sag, it trains your muscles to hold them up, so I'm going with that! Kircubbin2000 could you be more specific please? I did see an advert for 'The most comfortable bra ever' and I think it was from M&S but I couldn't find the one they meant when I searched.
