Runs very small!

  • Fit: Runs small
  • Size Bought: Medium

32AA 5’9” 120 pounds and I ordered the small because I thought based off the model photos, it would definitely fit me but it was too small! I truly do not believe those models are in a size small. The companies website actually gave me a size large based off their fit calculator but I settled on the medium. I haven’t decided if I’ll keep it yet or not so the tags are still attached as I’ve only tried it on but it is very well made and feels very supportive (for my size anyways). I used to have implants and I cannot imagine anything higher than a B fitting comfortably into this top!

Favorite swimsuit ever

  • Size Bought: S

I am like ~34b cup and the Small fits me perfectly. I got the sea green ecorib & the color is as pictured.


    Great material, love the ribbed look.

    Super Cute -- just not on me

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small
    • Size Bought: medium

    I thought this was a super cute top and is a color I've been wanting to add to my collection. Unfortunately, for women with bigger breasts, this is NOT the bikini top for you. I was spilling out quite a bit. I had my friend (who wears a 32B) try it on, and it looked SOOO cute on her! would definitely recommend for ladies on the smaller side :)

    Favorite top

    • Familiarity: I've used it several times
    • Fit: Runs large

    This is one of my favorite bathing suits - I purchased it in the black first and loved it so much that I purchased it in the sunflower color as well. I am typically a large but a medium fits just right in Vitamin A swimwear.

    Great Top!

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small
    • Size Bought: Large

    Got this for my wife, she loves it.

    Her words - This top is exactly what I was looking for. Something flattering but also comfortable and I dont feel like anything is going to fly out unannounced at the pool. The texture is a nice addition as well. I would say it runs small in the cup size.

    All The Right Places

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: XS

    Color appears orange in some photos. Yellow is the true color. I am a 32B, bought the XS and it fits perfect. Almost a bit snug but I prefer to feel held in. Good side boob coverage. :) Ladies you know that is important.

    How to Measure:
    For best results, take measurements over your underwear.
    Cup Size:
    Match your bra cup size.
    Measure under your arms, around the fullest part of your chest.
    Measure around your ribcage directly below your bust. This is not the same as your bra size.
    Measure around the smallest part of your waistline, keep the tape a bit loose.
    Stand with feet together and measure around the fullest part of your body.
