Modification: For the suit all I did was omit the back band, I simply kept it open and also added a clasp at the neckline instead of tie bands. On the kimono I added trim to the openings of the sleeve and hem. See the tutorial on making the kimono here.
Notes: I have still yet to wear this suit in the water, I have worn it boating a couple times and on the beach. I do wear this double gauze kimono all the time though!
