The below info is for govt swimming pools under the control of LCSD dept.
Speedo briefs for men is fine, Thong bikini on a female can get effiy depending on the staff, there is NO rule saying you cant wear one, the rule just says "Before you enter the pool deck area, make sure you put on a proper and clean swimming suit.".
Define PROPER is the hard question, if the female wants to wear a thong bikini, best to use common sense like wear a towel around your waist when coming out of the changing rooms and go the big pool, stay away from the kiddie pool where you are bound to piss of the MOMs who may or may not complain.
I personally have no issues with ladies wearing thong bikini
Pools are not open and since it's indoor pool season at the moment and another wave might be brewing, it's not going to happen at least until outdoor pool season which is not that far away(April 1st). We'll have to wait and see... Pools were open in the fall for a couple of months.
I just noticed a positive sign. I went by the local outdoor pool and it has just been refilled. It could be that they are just following their yearly maintenance schedule or perhaps gearing up for a 1st of April reopening if we are lucky.
That would be good news for most of us non snowflakes who ate quite happy to swim in the sweltering heat of April, May, June...
