  • Beautiful, Colorful, Fun Swimsuit!
  • I am a new customer to Bare Necessities and I am impressed with their customer service! This suit is well made, colorful and fun. I wish I could have kept it for my month in Florida in March. Unfortunately the bust was way too big for me even though the rest of the size 18 fit well. I am 5'9 and it was long enough and a flattering fit for a plus size gal. The description on the suit stated that the bust sizes were very large for sizes 18 and up. That is why I had to return it. The return process and return postage made it very easy and I even received an email telling me where my package was located on its way back to BN company and when I can expect my refund.. Very impressive!!
