My wife is 7 months pregnant and I'm surprising her with a mum-to-be spa day and massage. She's been really struggling with maternity clothes that fit and I want to make sure she has a swimsuit that she'll be happy and comfortable in for the day, without ruining the surprise (if I ask her to buy herself one she'll definitely know why, as she's dropped a few hints about a spa day!!)
Any recommendations of ones that have been comfy with a big, quite low bump?
