Quick Answer
Modern scrubs aren't “see-through” the way most people assume. The real problem is the loose-cut neckline that gaps open when you bend over a patient — exposing what's underneath. Thin-fabric translucency is secondary. The fix is one well-fitting underscrub that stays put when the scrub top gaps and adds opacity at the same time.
You're three hours into a shift. You're bending over a patient to adjust an IV line, or reaching down for a chart, or sitting low at a workstation — and the front of your scrub top falls forward and away from your body. What's underneath is suddenly visible to anyone who's facing you. Or you're standing in the breakroom and realize the outline of your bra is visible through your white scrub top. Either way, the moment lands the same: a quiet "I am too exposed right now" that follows you the rest of the shift.
This isn't a fluke, and it isn't only about fabric. Here's what's actually going on, and the four things that fix it.
The real problem: scrub tops gap open at the neckline
Modern scrub tops are cut intentionally roomy — for comfort, for ease of movement, for layering over various builds. The trade-off is that the neckline (almost always a V-neck or scoop) sits loose against your chest, and any time you bend forward, reach down, sit low, or lean over a patient, the front of the scrub top falls away from your body. What's underneath is visible to anyone facing you from above or in front.
This is the version of "see-through" most nurses actually deal with day to day. It's not about fabric being translucent — it's about the geometry of a loose top moving with a person who's bending and reaching all shift.
The fix isn't a heavier scrub top. It's a layer underneath that stays put when the top gaps away.
The secondary problem: scrub fabric also got thinner
There's a real translucency issue on top of the neckline-gap issue. Older 100% cotton scrubs were typically 200–250 GSM (grams per square meter). They were opaque on most skin tones, even in lighter colors, even on bigger busts. They were also hot, slow to dry, and didn't breathe well under PPE.
The modern scrub revolution — driven by brands like FIGS, Cherokee, and Mandala starting around 2015 — moved the category to lighter, performance-oriented fabric blends. Common modern scrub fabric is 70–80% polyester or nylon, 15–25% rayon or modal, 4–6% spandex, at around 140–180 GSM. That's almost half the fabric weight of an older 100% cotton scrub.
Lighter fabric breathes better, dries faster, and feels more comfortable under PPE. But it's also more translucent, especially in lighter colors — and especially when stretched across the body or pulled tight at the bust or shoulder. It's the secondary visibility issue, behind the neckline-gap problem.
What can be visible through (or down) modern scrubs
The two visibility paths combined produce, in rough order of how often nurses report it:
- Bra straps or cup at the gapped neckline — most common, happens whenever you bend or lean
- Bra outline through the fabric itself — particularly on lighter scrub colors
- Tattoo visibility — large or dark ink shows through pastels and whites
- Skin tone variation — birthmarks, scars, or natural skin tone variation
- Bra color — black bra under any lighter scrub is the worst offender for through-fabric visibility
- Camisole or thin t-shirt seams — if your "fix" is a camisole, the seams of the camisole now show through
Uniform policy might or might not address this directly. The unspoken rule on most units is just "don't make it obvious." That's hard to control if your only barrier between you and visibility is a loose scrub top.
Why modern scrubs aren't the enemy
Before getting to the fix, an important caveat. Modern roomier, lighter scrubs aren't worse than older 100% cotton ones. They're better at their main job: keeping you comfortable through 12-hour shifts in PPE, in hospitals that run between cold ORs and warm patient rooms, where you sweat through changes you didn't expect. The looser cut and lighter fabric are features, not bugs — they just have a side effect (neckline gap + translucency) that needs solving.
The right response isn't to go back to tight, heavyweight cotton scrubs. It's to add a layer underneath that closes the gap and adds opacity without sacrificing the breathability of modern scrubs.
Fix 1: Add a well-fitting underscrub
The simplest and most effective fix, and it solves both problems at once. The right underscrub does two things:
- Stays close to your body at the neckline so that when your scrub top gaps away, the underscrub is what's visible — and it's intentional
- Is opaque enough on its own that it blocks any through-fabric visibility from a translucent scrub top
What that means in fabric and fit terms:
- 150–200 GSM — light enough to disappear under your scrub top, dense enough to be opaque
- Tightly knit construction — open-weave fabrics aren't opaque even at high GSM
- Fitted, body-skimming cut — loose underscrubs gap with the scrub top, defeating the point
- A neckline that sits at or above your scrub top's neckline opening — usually scoop or low V
On color: treat the underscrub like an accessory at the neckline, not something that needs to disappear. Many nurses pick a pattern or contrasting solid that complements the scrub color — a polka dot or small print at the gap reads as deliberate, not accidental. If you want the look closer to invisible, a near-skin-tone neutral works.
The window test for opacity: hold the underscrub fabric up to a window. If you can see your hand outline through it, it's not opaque enough for under white scrubs.
Fix 2: Pick scrub colors and fabric weights carefully
Not all modern scrubs are equally see-through. Some line-specific picks:
- Lighter colors (white, pastel pink, sky blue, light grey) — show through worst
- Mid-tones (navy, ceil, hunter green, burgundy) — show through least
- Black and charcoal — show through least of all, but show every speck of lint
Within a given color, fabric weight varies by line and brand. The same FIGS line might have a "Core" fabric (lighter, more see-through) and a "Premium" or "Classic" fabric (heavier, more opaque). Reading the fabric specs before you buy makes a difference.
Fix 3: Bra strategy
For nurses who don't want to wear an underscrub but still want to reduce visibility:
- Match your bra to your skin tone, not to your scrub color. A nude bra is dramatically less visible than a white bra under white scrubs.
- Use seamless or molded-cup bras, not bras with lace, embroidery, or visible seams.
- Avoid black bras under any light scrub color — the contrast is what makes them visible.
- Wireless / soft cup bras are often more comfortable for 12-hour shifts and the lack of underwire bumps reduces shape visibility.
This is a halfway fix. It reduces the problem; it doesn't eliminate it, especially for bigger-busted nurses or under white scrubs.
Fix 4: Camisole / tank under scrubs
A camisole or light tank under scrubs is a partial fix. It adds opacity at the bust and at the seams, which solves the worst part of the see-through problem. But it doesn't add warmth, it doesn't wick sweat well, and the camisole seams themselves can show through both layers.
For nurses who only need opacity (not warmth), a high-quality fitted scoop-neck camisole is a decent budget alternative to an underscrub. For nurses who also want warmth, wicking, and longer wear, an underscrub is the right tool.
What we built for this problem
Our AeroKnit Seamless Long-Sleeve and SilkSeam Short-Sleeve underscrubs were both built to pass the under-white-scrub opacity test. We wear-tested early samples under white FIGS scrubs and rejected the fabrics that showed through, before settling on the current blends. The opacity test is one of the four things we test for in every fabric we use — alongside warmth, wicking, and 18-month wash durability.
The fabrics page has the full fabric breakdown including GSM and composition for each.
