To order Reiss petite size even though I’m 5 ft 4 ( and a half )

[Souredgrapes]

I only were flats or small heels . I’m between a Reiss 8 and 10 so I regularly order a 10 but need the items taking up a lot and sometimes cinched in . So I’m wondering if anyone my height has ordered a petite and got away with it .
The reason I’m asking is the chocolate jumpsuit I want is only available in size 8 regular . I’m wondering if I might get away with a petite size 10 ?

I think their petite lengths always seem to anticipate serious heels to make them work so I would say expect to need to take the length up
