I appreciate everyone minds. However , by that 142 cm, I consider, and it is IMO, logical to be length of her going from shoulder up to feet. (My unproved hypethesis). To try an inverted method. To check Tatiana's height in another 1913 photo (I think years is correct) in this one, comparing with Olga's, (from 1913, taken by P. Gilliard). We took their height's to be 158 and 163.
I measured Olga's height to be 9,5 and Tatiana's to be 10 cm long. Then after adjustment, we would be sure, if those length are correct.
O:T = 9,5 : 10 => 158:163 =9,5:10 => 0,9693... (left side) is nearly identical with 0,95 (right side). So, I have two conclusions : The first is that girls were approximately 158 and 163 cm long in 1913, and the second one that measurement of 142 cm of Tatiana's skirt (Court Grown) considers length from feet up to shoulders. ;-) - since results matches. Of course, they grew up each month, but we can circulate around these lengths.
----------------------------------
On regarding their 1913 measurements of Regiments dresses, I think they are pretty odd, I measured at both of them 11cm long regimnts, while their skirt measurement you gave differs for 36 cm. And almost nothing matches.
Ah, thank you for explaniation about tunics/bodices. Olga's was longer. It is 4,5 at Olga and 4 cm at Tatiana.
So, it would be -- 35:31= 4,5:4. And it matches!! (1,1290...nearly 1,125). It means that lengths of bodices are correct. I repeat, to make precise results is not so available. But they are almost as same heights. Only, I don't know if they wore heels. I am sure that Tatiana was a bit taller
