Congratulations for the big step!

I will share with you my golden rules about bra wearing. Keep in mind that I dont (yet?) need a bra, so if I wear it is mostly to satisfy my crossdressing/underdressing fetish.

1) Men will not notice a non padded bra. Women most likely will.
2) Wear pattern if you want to disguise the bra lines
3) A sports bra's lines will look like a vest. Thin bra straps will always look like a bra. Women are likely to notice either way unless you wear 7 layers.
4) The top layer makes the difference. Wear a larger t-shirt on top of the bra to create some extra creases, then wear a soft hoodie on top and it'll be very hard to spot the bra lines. But if you then wear a tight coat on top of the hoodie, all lines will magically reappear because all the fabric will be squashed down.
5) Golden rule: wear a bra ONLY if it makes you feel comfortable enough to enjoy your day. The thrill is nice, but if the thrill turns to fear, then stop, reconsider, and evaluate other options (different time, place, bra type, clothing...)

Thank you Shirazmn, I think I have read almost every one of your posts.   You always offer great insight and I think our sizes are fairly close. 

I keep telling myself I do not need a bra. My breasts aren't big enough to justify wearing one.  But wearing one yesterday, I was really taken aback how good having the support felt.  And how much better my shirt fit.  I am always in male mode.  The idea of wearing a bra while in male mode feels contradictory. But the support the bra gave actually made me look more masculine.  Which made me feel more masculine and confident.  

I prefer a little snugger fitting t shirts.  I think someone seeing the imprinting of a men's tank top under a t shirt draws the same suspicions as a sports bra under a shirt. But without a bra my nipples show and my shirt drapes. Kind of a catch 22.  

Maybe I am big enough to bra.  I think I will be wearing one more often in situations I think it would be benefit.

I have the same issue with sports bras they all show through, so I discover seamless invisible bra tops a while back and they are brilliant.
The ones I buy are from Marks and Spencers, but they are easily available on Amazon and places like Shein.
They are slightly padded so hide my nipples ( & piercings!) they are really comfy and invisible under all my shirts, t-shirts apart from a couple of of really skinny thin material tees.

I will check those out.  I had my nipples pierced for years when I was lifting weights and had a strong chest.  I just took them out a couple years when my chest wasn't looking quite like a body builder anymore. Sometimes I wish I had the piercings back to draw more attention to my breasts.

I wear a bra almost everyday, all day, because I need to.  I have breasts.  I live in small town America and don't want to be the subject of 
scrutiny.  So, how does my bra not get attention?  I have tried all kinds of bras.  If you don't want to draw attention take a look at Rhonda Shear invisible body bras on Ebay.  They come in all kinds of colors and support like a sports bra.  You can get packs of three for around $25.00.  Best of all...unless your shirt/blouse is sheer or transparent, they have no "tell tale" signs of straps or clasps.  I wear them to minimize jiggle and nipple pokies.  They work great.
    Only reveal is if you're sweating heavily, the sweat will saturate your shirt first and present a dry bra shaped image, and after everything dries...the bra shape will remain till it dries.  It's still easy to conceal in a black or dark colored gym shirt.

Thanks, I will look into these. I spend much of my time in small town America.  Jeans and pearl snaps are a staple in my wardrobe.  I spend a lot of time in the summer heat outside working.  I am the new guy town and sure wouldn't want to be known as the new guy that wears bras.

Hey Perk, I found these, I don't recall how or who pointed me in the direction, but I received them today and have been wearing one ever since (except when I was noogling). They're very low profile and so comfortable.  I can wear a tee that I bought before I started my journey (the first Xl tee I've bought in years) and, other than the size of my breasts, they don't print. No clasps, no slides, but I'm supported. I'm going to be ordering more since I'll apparently be needing them more now that the noogling is having visible, sustainable results.

I got the Large, as a self-measured 42A/40B.

I found that bras like these are very stealth: https://www.amazon.com/BESTENA-Seamless-Comfortable-Everyday-Removable/dp/B07DGPZM9S/
On Ebay you can find some that are made of an even thinner fabric. Their wide straps made of thin fabric makes them super stealth.

You can also find camisoles with hidden bras (slightly padded). https://www.amazon.com/Knuffnee-Women-Shelf-Cotton-Undershirts/dp/B0BXP7975L
These too are practically undetectable from the back, but the padding will indeed add some shape to the front. Under a coat or a hoodie nobody would clock them.

 I just gave you two random examples. May brands make clothes like these.

I ordered a pack of these. They will be in tomorrow. They very comfy. I’m excited to try them. The thin straps aren’t noticeable?

That first bra attachment is very similar to what I have now I wore all day today under a tight tshirt. I wasn’t concerned once someone might notice. The thin wide straps are invisible. I will get more like these. 
i think I want to order camisoles.

Again, I've only had them a day; but I wore it all day under a tee that every single other bra I have clearly prints and I saw nothing. Under and undershirt and button up I give it no chance. I'm excited for you because I know how good they feel on me.

I am excited for them to be delivered today.  Im going to put one on as soon as it gets here.

Well? This isn't a voyeuristic or other request for feedback. I've worn these all week and it feels like a thundershirt, if you're a pet fan, for me. They're helping to aid front projection and cleavage development. I'm loving them and hoping you are too.
