When I was 6weeks po I first went to Victoria’s Secret. I think they’re sizes run small, as I was measured at a 30DD. I also went to Boux Avenue the same day but just got a push up bikini, they measured me the same. I heard Debenhams is pretty good, they have a wide selection of luxury bras. I’m not a fan of M&S bras but if you’re looking for cheaper and comfortable bras it’s good.
