For my Jacuzzis (I've had two) they had just plain white/off white button down shirts. The vest (see here
) were made by my friend Teresa and I. Vests aren't particularly hard to make--she made it out of brown fabric in like, 20 minutes. The collar was a little harder, but again, if you find a pattern for a dress shirt and use that pattern it shouldn't be a problem. The stripes we measured out, taped out, and painted with fabric paint. Hope that helps!!
