A change of buttons and belt buckle might give this 1957 dress by Creators Studios a slightly different look. Rather than sewing the buttons on, a shank can be used. Detailed instructions for shank buttons is on page 19 of the Womans’ Institute book, Drafting and Plain Dressmaking (Part 4) from 1920. You make a little eyelet hole for the shank end to tuck into.
Another way to change out the buttons is illustrated on page 18 where the buttons are sewn onto a strip and buttoned through two sets of buttonholes. In the dress above, the top button might be a stand-alone button, not attached to the main strip. Notice the location of the keyhole in the buttonholes of the dress. The button appears to be seated in the lower end. If you were going to make the buttonholes by hand, the underneath band would be a perfect place to start out. Another reason to use buttons on a strip is to avoid laundering unwashable buttons. It would also not be necessary to unsew and resew buttons before washing or cleaning outfit.
Here is the illustration of the 1915-1920 vest-and-panel dress that uses the button strip or shank buttons
