I liked the video. The girl and boy have been doing good at swimming. Very well! The swimwear does affect the swimmer's body movement. If the swimwear is not properly fitted then, it may disturb doing swimming, especially for men. I have recently started wearing Skiviez Bikini. It is very comfortable and relaxing. The fabric is very soft, it doesn't create chafing.

The suits that they are both wearing are so beautiful. And he is so manly in his swim with her.
Super that your nephew is getting a chance to learn synchro.

He has gelled his hair. More males duets are doing that.

Her makeup is just perfect and she has a super choice of a suit.
