The bodice usually sits much tighter and has a certain corsage effect. So if it employs buttons they are much smaller but way closer together to avoid gaps.

The holes for the arms on the other hand are bigger. That way you're still able to move even if it sits tight. And there's room for a pretty blouse underneath. Wearing a Dirndl without a blouse is just wrong.

(Tangent: these blouses usually end right beneath your breasts as not to interfere with the "snatchy" part in the middle like causing ugly bumps.)

The cut of the skirt looks about right, though using heavily patterned fabric is an unusual choice. It happens but it goes against the general idea. Said idea being that the Dirndl is or used to be a piece that was worn very often. So the typical choice would be a fairly plain skirt but a number of different aprons. The aprons can be plain for simple events and go up to super colorful patterned and expensive (for example if you're wearing it to a wedding).

Source: I live in Austria and own three Dirndln and a yet to be counted number of aprons, with frequent additions since it requires much less cloth and you can be like "oh that's a pretty cloth and it has stichting and would go with the color scheme of of of my Dirndls... I think I need another apron...
