Aly on Swim Trunks 6.10: Please no speedos:) Go with something tasteful. Length is important So go for something that is around knee length.
Sarah on Swim Trunks 6.10: Shorter than knee length is okay only when you vaca to Europe, or Australia. Make sure it's not see through, please. Too many options to go with boring here, especially when it's all you are wearing.
