The real problem

Every body is different.One size label never fits all of them.

“

Even Rent the Runway ships two sizes to every customer — just in case. That's how broken online sizing is.

You shouldn't need two sizes. You should just know.

Full bust
Tight across the chest, loose at the waist. FitCheck catches the exact chest measurement and tells you before you buy.
FitCheck catches this ✓
Petite
The pants always fit everywhere except the length. FitCheck knows your inseam and flags it on every single item.
FitCheck catches this ✓
Broad shoulders
That top is going to be snug across the back. You just don't know it yet. FitCheck tells you before it ships.
FitCheck catches this ✓
Curvy
The waist fits a size 8. The hips need a 10. FitCheck maps every measurement independently — not just one number.
