Skip the letter on the tag: match your chest or bust measurement to the product page’s chart, then size up if you’re between sizes.
A flag-print sweatshirt from one brand can fit like a second skin while the same letter from another hangs off your shoulders. Target’s women’s flag pullover runs a size S bust of 35–37 inches, but Forever 21’s open-knit flag sweater lists an S at 34–35 inches — same letter, very different room. That gap is why most people guess wrong.
The fix: measure once, read the chart on the page you’re buying from, size up if you’re between numbers. Below is the measuring order that holds across brands, plus the mistakes behind most returns.
How To Measure For A Flag Sweatshirt
Measure your chest or bust at the fullest point with the tape level and snug but not tight, then compare to the seller’s chart — not a size you remember from another brand.
- Chest or bust first. Wrap the tape around the fullest part of your chest, parallel to the floor, arms relaxed. Forever 21’s guidance specifically calls for relaxed arms.
- Waist and hips second. These matter most on women’s fitted and fashion-cut styles, which taper more than a standard unisex hoodie.
- Garment measurements third. Check listed sleeve and body length — a chart that fits your chest can still leave your wrists exposed if you’re tall.
- Fabric last. Cotton sweatshirts and hoodies may shrink somewhat, so factor in whether the item is pre-shrunk or cut with extra room.
Tape position matters: a chest measured with arms crossed or the tape riding up your back reads an inch or two small — exactly how a “true to size” order arrives too tight.
Women’s Vs. Men’s Flag Sweatshirt Charts
Women’s flag styles are charted by bust, waist, and hip; men’s and unisex hoodies are typically charted by chest alone — so a women’s S and a men’s S are not comparable number for number.
Target’s women’s crewneck flag pullover lays out a full three-measurement range: S is a 35–37 inch bust, 29.5–31.5 waist, 38–40 hip; M moves to 37–39.5 bust, 31.5–35 waist, 40–42.5 hip; L runs 40–42.5 bust, 35.5–38 waist, 43–45.5 hip; XL tops out around 43–44 bust, 38.5–39.5 waist, 46–47 hip.
Forever 21’s women’s chart starts smaller: XXS at 31 inches bust, XS at 32, S at 34–35, M at 35–36, L at 36–37, XL at 38–41. Target’s S next to Forever 21’s S is a two-inch spread before either garment leaves the warehouse.
Men’s and unisex flag hoodies — like the Walmart USA flag print hoodie — follow the chest-only convention and are described as a loose, soft cotton casual fit with drawstring and kangaroo pocket. A loose cut builds in slack; a fitted women’s pullover does not.
Size Up Or Down? Reading The In-Between Numbers
If your measurement lands between two sizes, take the larger one — unless the listing says the item is oversized or you want a close fit.
Layering a tee under a flag sweatshirt eats room, cotton can tighten after the first wash, and a size that fits exactly on day one has nowhere to go. Sizing up gives a relaxed drape that still looks intentional on a graphic pullover.
Two caveats. Construction differs: an open-knit sweater like Forever 21’s $24.99 flag style (down from $29.99) stretches and breathes differently than a fleece-lined hoodie, so the same chart number can feel looser or tighter depending on weave. And confirm return and exchange terms before you commit — especially between adjacent sizes or with cotton that may shrink.

The Mistakes That Send Flag Sweatshirts Back
Most sizing errors come from trusting the letter on the tag instead of the numbers on the page — the rest from comparing the wrong charts.
- Assuming S, M, L, and XL mean the same thing at every retailer. They don’t, and the flag design has nothing to do with it.
- Holding a men’s chest measurement against a women’s bust chart as if they’re equivalent.
- Ignoring body and sleeve length, which bites taller buyers hardest.
- Treating “American flag sweatshirt” as one product — the styles run from a women’s crewneck pullover to an open-knit sweater to a men’s drawstring hoodie: different fabric, fit, and price.
- Confusing a knit sweater with a fleece sweatshirt. Stretch, warmth, and layering all shift.
- Quoting a price without rechecking the live product page, since listed prices change.
None of these are exotic. Each one costs a return shipping label.
FAQs
Should I measure over clothes or on bare skin?
Over a thin shirt or on bare skin, not over a bulky sweatshirt. The chart numbers describe your body, not your layered outfit. If you’ll wear something thick underneath, add roughly an inch to your chest or bust measurement before comparing.
Do cotton flag sweatshirts shrink after washing?
Cotton garments may shrink somewhat, though pre-shrunk styles shrink far less. Wash cold and air dry to limit it. If a listing doesn’t say pre-shrunk and you’re between sizes, the larger size is safer — it leaves room for slight shrinkage without turning snug.
What if the size chart lists no waist or hip numbers?
Many men’s and unisex hoodies publish chest measurements only, which is normal for that cut. Rely on chest plus any garment measurements the page provides, like body and sleeve length. For women’s fitted styles, a missing waist or hip figure is a reason to check the return policy before ordering.
