A Korean spa requires full nudity. It is segregated by gender. Depending on the state, nude w/o cover is ok for massage if there is agreement by therapist & customer (i.e. TX).

@kaizon I guess the Korean spa doesn't even provide a disposable underwear. Some places provide a disposable underwear. I prefer to wear my own thong underwear for massages and luckily, the spa I go to allow me to do that. I don't think facials would require full nudity at all. I don't know because I only go for a massage. I agree with the gender segregation at the spa.

Worn a thong for 4-5 years at the same spa. Visiting daily with my routine certainly complaints were issued with management. Although no warnings or statements made about my thong swimwear. When new female manager was hired then judgement and issues of my thong were made. 

Fun as it lasted. Just before my banishment from the spa. Young 39 year old single mom commenting  enjoyed how daring thong swimwear i wore. She admitted closely watching other female reaction upon me. Saying women would act non responsive as i walk across their line of sight sitting in hot tub. The women wide eyed would follow me along pool deck, she said. Friendly 39 year old single mom revealed  to me enjoying reactions from other women. Even though i could not discern doubting anyone looking upon me in the thong. She insisted gals definitely looked subtle as they were for whatever reason.  

 Her words made me feel better unfortunately this coincided banning from wearing the thong in the spa. 

Speculating that few Karen’s found my swimwear all to revealing. Therefore threatening to unsubscribe as member to the spa. Even though many never used the aqua facility themselves. Many complaints from observing me from  outer window looking  into the spa. Since i had no sense of modesty people felt uncomfortable let it be known to managers attention. 

Whose idea to build wall around the hot tub is confusing. Only reason some modest women don’t want to be seen sitting in the hot tub from pool swimmers or outer wind. 

@mack_back I don't understand about being banished from the spa just because you wore a thong swimwear for the pool there. I think it should be ok to allow thong swimwear at the pool or jacuzzi. Building a wall around the hot tub, well, I don't know the reason for having a wall around the hot tub. Maybe because so that people can have some privacy, I guess, while sitting in the hot tub. In that case, there is nothing wrong with wearing thongs behind the wall! The 39-year-old and her comments, well, that's not any of her business about you wearing thongs. It's only your business and no one else's. Personally, I wear thongs when I go to the spa for a massage. Wearing a thong while laying down on the massage table makes me feel good actually. Maybe you could get a massage and wear a thong. I'm sure no one is going to bother you because no one is going to see it.

BeachGirl: What i meant is management wanted me to agree wearing more to coverup. Didn’t feel anything wrong and years wearing thongs to the spa until now. So i agreed if i’m being picked on wearing thongs i will stop visiting the spa anymore since i’m not welcome to wear what i want. After couple weeks female manager called noticing i was absent visiting the spa from her records. She wanted to be clear that wearing a speedo is allowed. But i said, don’t find anything wrong with my past swimwear and will not compromise the style of clothes. She insisted i was welcome to visit. I declined her offer finally goodbye. No the 39 year old single mom was very complimentary. Wishing she can wear such sexy swimwear to the spa herself. Later she learned meeting me outside the spa realized being banned wearing thongs at the spa was unfair and disappointing. Feel being rejected by fellow spa members that my thonging offended others. Don’t want to be in atmosphere where i’m not welcome. 

Some spa members have commented don’t blame me wearing what i do. If they had body like that they wear the same. 

Problem i was told by two brave employees male and female  at the spa while in the pool. That complaints are effect of my bulge being prominently showing. Can’t help it or as much women with voluptuous  breasts. Feel i’m being picked on not ashamed of my bulge shape in a thong. Although thongs i choose to wear compliment my shape very well. Observed women walking outside spa after they changed or completed studio session. Found few young gals preparing their phones and pointing them while climbed metal staircase leaving the building. Meanwhile large wall window along staircase can observe me standing in the shallow pool. Few smirks from the gals or they used it as evidence to condemn and proof of my thonging and later banning. 

Enjoying stunned  awe, open mouth reaction from friendly aqua spa female trainer i know for many years. Whenever i entered spa deck from the men’s change room. Waving hello to her only for her to get over my matching swimwear bottoms. As she wore only mine were thongs then bikini briefs. 

Only seen few women attire thongs to the spa over many decades i visited. Suppose i keep it as fond memory enjoying the fellow thongers. Remembering asian mom and beautiful daughter in the hot tub. Daughter ignoring me when i entered sitting close by in my camo thong. Mom had wide eyed shock noticing my whale tail as i stood across from her noticing my thong. Daughter however kept stoic straight face minding her business. Only later when both mom and daughter stepped out of hot tub. Lingering on the pool deck beside the hot tub steps. Noticed beautiful daughter in black one piece thong. Unusual they stood gathering their towels. Almost as if wanting to show off her thong while mom in full bikini. Trying not to look ignoring them i couldn’t help but notice sexy multi string one piece high cut thong. Only when they both walked turning around to female change room i could visually stare admiring her backside. Maybe me projecting but felt daughter with the mom wanted to show off the thong swimwear. Or very least wanted someone acknowledge or compliment her thong. Since gals in the hot tub stayed mute when i entered in my thong. Decided to treat them the same.
