Ratings & Reviews

Love but had to return


I was so excited to see that Speedo was introduced to Penningtons. I have been searching for a swim suit for awhile. So when I seen this one I instantly had to order it. According to the size chart I would be a 22. So I got my swimsuit and tried it on. And it fit but was way to short in the body. So unfortunately I had to return it . So sad, cause it's a beautiful suit.


Yorkton, sk


The ultimate plus size bathing suit!


Most bathing suits I bought at penningtons/additionelle dont incorporate a big stomach into their fit, which ends up pulling my breasts down and makes them look saggy. Usually not enough fabric to perk my breasts up to a normal height. But this one has enough fabric for a regular torso with what feels like a built in sports bra for support. I lane swim and excersize in the pool quite a bit and its hard to find these. I would recommend this to a plus size woman who wants to swim more. Also wish it came in more colours like dark grey or black.
