Nine blocks.
Not one, resized.

02 · Others vs FflirtyGo
Same size on the label. Cut two different ways.
Most brands grade one pattern up and down until the tag reads your size. We draft a separate block for every size. Here's what that changes on your body.
Put your chest in the box below. We'll tell you which of the nine is yours.
Stop guessing your size
Your exact size. In 10 seconds flat.
Punch in your chest. We give you your size in a clean, roughly 6″-oversized fit, plus the size up if you want it baggier.
All nine sizes, each drafted on its own block
Measure over a t-shirt, snug not tight.
How to measure your chest
- 1Wrap a tape around the fullest part of your chest, level all the way round, across the shoulder blades at the back.
- 2Keep it snug, not tight. Arms down, breathe normally. Don’t puff up or suck in.
- 3Read the number in inches. That’s what goes in the box above.
Over a t-shirt is fine. No tape? Wrap a phone-charger cable around, pinch where it meets, then measure that length against any ruler.
| Size | Garment chest | Your chest | Length |
|---|---|---|---|
| S | 44″ | up to 38″ | 28″ |
| M | 46″ | 39–40″ | 28.5″ |
| L | 48″ | 41–42″ | 29.5″ |
| XL | 50″ | 43–44″ | 30″ |
| 2XL | 52″ | 45–46″ | 30.5″ |
| 3XL | 55″ | 47–49″ | 31″ |
| 4XL | 57″ | 50–51″ | 31.5″ |
| 5XL | 59″ | 52–53″ | 32″ |
| 6XL | 61″ | 54–55″ | 32.5″ |
Oversized cut. The room is drafted in, not left over. Garment chest is the tee. Your chest is you, with our oversized room already allowed for. Same maths as the fit finder above.

05 · How it's cut
A 3XL that fits like a tent up top and a crop at the hem is a scaling problem.
That's what happens when one pattern gets multiplied nine times. Every measurement grows at the same rate, including the three that shouldn't. The shoulder, the armhole and the hem end up wrong in both directions at once.

One pattern, scaled
Wide enough round the middle. Wrong everywhere it touches you.

Nine patterns, drafted
Nine sizes, nine blocks. It costs us more and it's the entire reason it fits.
The yoke
+5.5"Grows with the chest, S to 6XL, so the shoulder seam lands on your shoulder and not halfway down your arm.
The armhole
Sep.Graded on its own, not stretched along with the body. The underarm was always the real complaint.
The length
+4.5"Its own grade per size, so the hem clears the waistband and stays there when you sit down.
6XL is the best-selling size in these tees. Two in three go out in 3XL or bigger.
06 · The fabric

240 GSM combed cotton terry. Brushed loop-back. Pre-shrunk.
Four numbers instead of four adjectives. Heavyweight enough to hold its shape at the collar and hem, open enough on the inside to move air on a hot afternoon.
Weight
240GSM. Heavyweight, so the collar and hem hold shape past month two.
Knit
TerryBrushed loop-back. The inside face is open, so it moves air instead of clinging.
Yarn
Combed100% cotton, combed for a smoother, stronger surface that doesn't pill early.
Finish
Pre-shrunkWashed before cutting, so what you measure is what stays.
Ribbed collar · twin-needle hems · shoulder-to-shoulder tape

08 · Why this exists
“For years, buying my size meant taking whatever a brand had scaled up and hoping it landed. None of it was drafted for a bigger frame, so we drew the whole run ourselves, a separate block for every size.”
09 · If it's not right
Then it's on us to fix. Not on you to live with.
The size you order is the size you keep. That's the whole point of the nine blocks.
