1,494. That is how many of the 83,353 in-stock dresses in our index are fully covered: long sleeves, a modest neckline, a hem at or below the knee, and no slit, sheer panel, cut-out or open back. Across the 100 stores we track, that works out to 1.8% of everything on sale, or about one dress in fifty-six. We counted on 24 August 2026. The numbers explain why modest dresses are so hard to find, and where the covered ones hide.

What counts as modest here
Modesty standards differ, so we measured two of them. The looser one is what our modest dresses hub applies by default: nothing sheer, no cut-outs, no open backs, no thigh slits and no minis. About 13,000 dresses clear that bar, roughly 15% of the catalogue.
The stricter one adds the two things most people actually mean when they say a dress is modest: long sleeves and a covered neckline. That is the count that collapses to 1,494, and it is the exact set behind our long-sleeve modest dresses edit. Everything below uses the strict definition unless we say otherwise.
Sleeves are the bottleneck, not hemlines
Each bar is measured independently, as the share of the whole catalogue passing that single test.
This changed how we think about the whole problem. The things people brace for (sheer panels, cut-outs, slits) are comparatively rare, and more than three quarters of dresses are already long enough. The catalogue fails on the top half of the dress. Sleeves knock out 88% of it before any other rule is applied, and necklines take most of what is left.
It also explains a frustration that shows up in every message we get about the site: filtering for length gets you thousands of results and almost none of them work. Length is the filter that removes the least. Two thirds of everything sold online (67.4%) is sleeveless outright; short sleeves add 14.1% and three-quarter sleeves just 3.9%.
Sleeves also turn out to be a reliable proxy for the rest of a dress. Among sleeveless dresses, just 13.1% have a modest neckline. Among long-sleeve dresses, 37.8% do, nearly three times the rate. A brand that bothers to cut a sleeve tends to have thought about the neckline too, which is why sleeve length is the single most useful filter to start from. Collared dresses are an even stronger signal: collars appear on 6.6% of the catalogue but on 30% of fully covered dresses.
A long dress is not a covered dress
Share of dresses at each length that pass all of the strict rules.
Counter-intuitively, the longest dresses are among the least likely to be modest. Floor-length inventory is dominated by evening wear, and evening wear is where strapless bodices, deep backs and high slits live: 49% of the catalogue is formal, and those gowns drag the long-dress pass rate below the knee-length one. If you are shopping by length, knee-length and midi are better hunting grounds than maxi. For events, start from modest gowns rather than filtering a general formal category down.
Where the covered dresses actually are
They are concentrated, and not where you would guess. 28 of the 100 stores we track have no fully covered dress at all, including some of the largest catalogues in the index, which are bridesmaid and going-out specialists carrying thousands of styles that never clear a single rule. Meanwhile one mass-market retailer, ASOS, accounts for close to a third of every fully covered dress we track, at a median price under $90. Volume beats intention: a store with 6,000 dresses and no modesty policy still out-stocks a boutique with 300.
The other reliable pockets are occasion-wear houses that cut sleeves as a matter of house style: Tadashi Shoji and Mac Duggal at the formal end, Club L London and Commense for everyday, Universal Standard for workwear through to 4XL. You can see the full list of stores we index on the stores page.
The practical takeaway: filter first, choose the store second. Going store by store means opening about fifty tabs to find one dress. Filtering across all of them at once (the entire reason this site exists) turns the same search into a single page. Start with every modest dress we track and narrow from there.
Does covered cost more?
Yes, modestly. The median fully covered dress is $149 against $125 for everything else, a premium of about 19%. The gap widens at the top: dresses over $500 pass the strict rules at 3.6%, roughly three times the 1.2% rate for dresses under $50. Fabric and construction explain most of it, since sleeves cost material and pattern work, and cheap fast fashion optimises the other way.
That said, the premium is an average, not a floor. The cheapest fully covered dress in the index is a $9 shirt dress, and there is real depth in the under $100 and under $150 bands, mostly from high-street retailers rather than modest-specialist labels.
How we counted
Every dress in the index is tagged from its own product photos by a vision model, which reads sleeve length, neckline, hem length, slits, cut-outs, sheer panels and open backs. Where a product title contradicts the photo tag, the title wins. Unknowns are treated conservatively: an attribute we cannot see does not count as coverage, so 1.8% is a floor rather than a ceiling. The figures here are a snapshot of in-stock inventory on 24 August 2026 and will shift as stock turns over; sleeve counts in particular climb every autumn.
One honest caveat: photo tagging is better at spotting an exposed neckline than a covered one, so a handful of genuinely modest labels score lower than they deserve. It biases the numbers down, not up, which is why we use the strict count as a floor and re-check the necklines by hand for the brands we feature.
Common questions
How many modest dresses are actually available online?
In our index of 83,353 in-stock dresses from 100 stores, 1,494 are fully covered: long sleeves, modest neckline, hem at or below the knee, nothing sheer, slit, cut out or open backed. About 13,000 more clear the looser bar of no sheer panels, cut-outs, open backs or minis, but have shorter sleeves or a lower neckline.
Which stores have the most modest dresses?
By volume, mass-market retailers win because they carry the most stock overall. ASOS alone accounts for close to a third of the fully covered dresses we track. By proportion, occasion-wear houses such as Tadashi Shoji, Teri Jon and Mac Duggal have the highest share of covered styles, because sleeves are part of their house look.
Why is it so hard to find a long-sleeve dress?
Because only 11.9% of dresses sold online have long sleeves, and two thirds are sleeveless. Every other modesty rule (length, slits, sheer panels, cut-outs) is cleared by most of the catalogue. Sleeves are the constraint.
Are maxi dresses more modest than midi dresses?
No. Floor-length dresses pass our strict rules 1.9% of the time versus 2.7% for midi and 5.2% for knee length, because most maxi inventory is evening wear with strapless bodices, open backs or high slits. Length alone is a poor proxy for coverage.
Do modest dresses cost more?
Somewhat. The median fully covered dress is $149 against $125 for the rest of the catalogue, a premium of roughly 19%. Dresses over $500 are about three times as likely to be fully covered as dresses under $50, but there is still real choice under $100.
We re-run this count as stock turns over. If you want the current version of the 1,494 rather than the numbers, it is one click away: browse the covered dresses.
Refynd is a free search engine for modest dresses. It indexes about 85,000 in-stock dresses from roughly 100 online stores and tags each one from its own product photos for sleeve length, neckline, hem and coverage, so you can filter every store at once for your own standard. Refynd sells nothing itself; every listing links to the retailer. How it works.
