I just read your other post, which was deleted. The one with the photos. Here is my response to that one:

I have to say, i thought this was a bot account. I then read your history.

My advice would be to delete the photo, so you're not leaving a personally identifiable trail online.

My short answer to your question, as I am low on time, is you are just fine. More than that, and must be feeling a bit low, to feel like asking.

My longer answer would revolve around self worth, not requiring other's approval, etc

I think you've got this. I hope you have a great time, with whatever is coming up!

cognitive dissonance

IMHO it's really all about you being worried about how others react. Speaking as a 50 year old guy, I would walk around naked if it was normal in society. Put the bikini on and stand in front of a mirror. Make sure you're confident that it looks normal (no tags still showing, nothing that is too revealing or pinching in the wrong spot or whatever... then put it on and go out in public and don't think about it. It'll be fine and nobody will think twice about it other than maybe saying "damn she's keeping herself in shape!"

It'll be fine. Don't let others get in your head so much that it determines what you're going to do or wear.

It's not just Bikinis. It's all swim wear, saunas in Europe, baths in Japan. It's just socially acceptable and expected in the right context, and that expectation plays a huge role in comfort. The context seems to flip a switch in people's brain.

People are right in saying it's context and consent, and it's not completely gendered. Men's swimsuits are basically just boxer shorts. Normally I'm not self-conscious about that, but a few months ago I signed up for a toddler swimming class with my son where I wound up being the only Dad, and suddenly I felt a bit exposed. I think the normalcy of walking around in nothing but a small pair of shorts kinda evaporated once I was the only man in the room.

The same way that pigs are food and dogs are not. Cognitive dissonance.

We are on vacation right now and my SO actually wears only the bottom of the bikini and goes bra less to the beach, because she says it's unfair I can free my nipples and she can not. Well that's pretty fair I would say?
We are European though and probably a bit less prude than US Americans.

Ehm, not the same... but I think that how everybody is dressed affects how we perseive our nakedness. Once i went in a trip to Brazil, and felt a little ridicule by how long my swimming shorts were. I ended up buying a swimsuit there... that I can only wear if i ever go back to Brazil.

I can’t speak from a women’s perspective, but wearing swimming trunks in public feels very different than wearing boxer shorts in public.

It does feel like going out in underwear, to a place where everyone is in underwear, and the people wearing full clothing look out of place. I don't even have a perfect body but grew up near the beach, saw every possible body type in swimwear. So I am comfortable enough looking near naked in public, since everyone is. It's nice.

social conditioning

People here saying consent (fair enough) but let me tell you, clothes are suggestive. There is more to suggestion and context than the actual content. Is anybody shocked to see a nude statue in a museum or something? Or in a painting? Now how about somebody wearing nothing but a g-string and a harness? You can argue the harnessed person in a gstring is less exposed than any nude. I say no. Clothing adds to the exposure sometimes. Underwear isn't meant to be seen, so when it's seen, it prompts judgement.

Swimming apparel is explicitly made from slightly thicker and very different material, keeping you from looking like you entered a wet-tshirt-contest. That alone is a big subconscious help. Or are you talking about the amount (or rather lack) of clothing?

I can't contribute much except that I've asked myself this question many times. I guess some underwear is see-through but other than that it's kind of the same attire.

I've never in my life been comfortable with anyone seeing me on a bikini, no matter how good I feel about my body. The "difference" between that and underwear or virtual nudity never permeated my brain 😂

Basically I think it's weird that they're treated so culturally different and don't feel comfortable in them myself, but also support the choice of whatever bathing suits people prefer or nudity in designated areas

Do what makes you comfortable.

You'll be out with family and friends, in an environment where most any swimsuit would be expected. Any lack of confidence would come from your own internal comfort, so you do you.

As a more practical suggestion if you're on the fence, wear a wrap? Then you can decide how you feel in the moment.

I just got done working a comic convention this weekend. You might be pretty surprised by the general lack of clothing most people wear to those things (calling it a "costume").

Just this weekend alone, I saw at least five guys walking around without a shirt, and I don't know how many women wearing things that showed basically everything. Like so tight and thin I could tell what kind and color underwear they were wearing.

And this was in Indianapolis, far from a beach or lake, right in the middle of downtown.

Something about feeling like a mom I guess? Idk I don’t have kids! xD For me, rocking a bikini = feeling confident about my body. I used to wear smaller bikinis when I was younger but now I find swim shorts much more comfortable, practical, carefree. Why are us women wearing small tight swim clothes anyway, that you gotta adjust, fuss with the strings, prevent the nip slip, etc. Meanwhile men wear comfy shorts? Well it helps that I’m not at that stage in my life where I’m looking to date or impress anyone lol.

I will say that if I were diligent about going to the gym and had a rockin bod, then yes. I’d probably wear that bikini to show off my hard work😉💪🏼
