Is there a super secure swim suit knot?

Question

Im heading to the lake for the first time this summer this weekend, and I've learned a few lessons from last summer. The guys I go with like to pull on the halter string of all the girls bathing suits, and I'd like to avoid that this time around. Simple bows liek I normally do can be easily pulled and untied while walking past, so Im looking for something that wont unravel so easily, but will be easy for me to undo when I take off my top. Anybody have any ideas?

Answer 1

double knot it

Answer 2

get a suit that clips either at the back or neck so you only have to worry about one part being untied and you can catch the suit before it falls. or just double knot it. just not too tight or you will never get it out.

Answer 3

Double knot it until it feels tight and good.

Answer 4

just a simple knot does it for me, and then when you have to take your top off, just pull the strap the goes around your neck, over your head so you can untie the knot.

EDIT - you could also knot it, then tie it in a bow. so when the guys pull on the bow, the knot is still there... they'll wonder why it isnt falling off!
