Most people who try going braless quit on day one, because they tried it in a thin white t-shirt, spent nine hours doing covert mirror checks, and decided it was not for them.
That is a sequencing problem, not a braless problem. You started on hard mode.
Start with the right top, not the hardest one
Work down that list rather than starting at the bottom of it.
A blazer, a denim jacket, a structured shirt or anything patterned requires nothing at all. Dark or textured knits are nearly as forgiving. Ribbed tanks, jersey tees and silky slips are where covers start to matter. A thin pale tee is genuinely difficult, and sheer is a separate decision entirely.
Give yourself a week in the easy two rows first. It stops being a project remarkably fast.
What actually gives you away
Contrast. A cover lighter or darker than your skin shows through pale fabric. Thickness is not the problem, colour is. Match your skin rather than your top, which is the opposite of most people's instinct.
Edges. A cover whose rim stops dead instead of tapering draws a visible circle. This is the single thing cheap pairs get wrong, and it is worth checking before you buy.
Movement. Standing still in front of a mirror is not a test. Sit down, walk, raise your arms. Clothes behave completely differently when you pose for them.
Going braless with a bigger bust
Two things are true at once here, and most articles only admit the first.
Going braless with a fuller bust is completely doable, and nipple covers handle the visibility part just as well as they do for anyone else. Buy larger covers, because surface area is what keeps them flat against more curve.
What covers will not give you is support, and on a bigger bust the absence of support is more noticeable in how things feel than in how they look. Some people are entirely comfortable with that, some are not, and some want a bralette or a light wireless option for long days and covers for everything else. All three are reasonable. Anyone telling you there is one correct answer is selling something.
For a specific event that genuinely needs lift, boob tape is the tool, not covers.
Going braless at work
The honest answer is that this depends on your workplace and your own comfort, not on any rule.
Practically: structured layers make it a non-issue. A blazer, cardigan or anything with body means nobody could tell if they tried. If your office is casual and your tops are thin, covers plus a slightly thicker fabric handles it. Start on a day you are not presenting to anyone, wear something forgiving, and see how you feel by lunch.
The thing people usually discover is that they were the only person paying attention.

Heat, sweat and long days
Clean, dry, product free skin is what makes adhesive work. Lotion and sunscreen are the enemy, and this matters more in summer when you are likely wearing both.
Good silicone covers handle heat well because they are not under tension, unlike tape or a sticky bra. Put them on before you apply anything else to your skin, and give them thirty seconds of contact so body heat can do its part.
A first week that actually works
Day one, wear a blazer or a structured top and go about your life. Day two, a dark knit. Day three, add covers under a ribbed tank. By the end of the week, try the jersey tee.
Do not start with white. White is the final exam, and we wrote a separate guide for it.
The short version
Start with forgiving fabric, match your shade, check the rim, and test it sitting down.
Bras are prisons. This is the parole paperwork.

Frequently asked questions
How do you go braless with big boobs?
Use larger nipple covers, since surface area is what keeps them flat against more curve, and start with structured or textured tops before moving to thin fabric. Covers solve visibility but not support, so for an event that needs lift, boob tape is the better tool.
How do you go braless without people noticing?
Three things: match your cover shade to your skin rather than your top, use covers with a properly tapered edge so no circle shows, and test the outfit sitting and moving rather than standing still in a mirror.
Is it okay to go braless at work?
That depends on your workplace and your own comfort rather than any rule. Structured layers such as a blazer or a thicker knit make it effectively invisible, which is why most people start there.
Do you need nipple covers to go braless?
Not always. Structured, dark, thick or patterned tops need nothing. Covers matter for thin, pale, ribbed or silky fabrics where the outline would otherwise show.
Does going braless cause sagging?
There is no good evidence that wearing or not wearing a bra determines breast shape over time. Changes are largely driven by genetics, age, pregnancy, weight change and skin elasticity. Wear or skip a bra based on comfort rather than on that worry.
How do you go braless in a dress?
Same rules as a top, with fabric weight doing most of the work. A lined or structured dress needs nothing, a thin jersey or silky slip wants covers in a matched shade, and a backless dress that needs lift is a tape situation.
