hello, i need some advice on ...
DW wants me to alter the shoulder/contour darts on a RTW dress to be worn to a nephew's wedding. The dress was chosen from a batch of various sisters's dresses. The reccomended alteration was suggested and marked with 2 safety pins by a gaggle of relatives during a dress trial/fitting session. The alteration was suggested to improve the bust/waistline appearance.
Dress is full length (%100) silk with slit to knee over one leg and fully lined with (%100) acetate (as the labels say) and zipperd down center back. Neck line is squared and there is some pintucking decoration on the front and it has very short sleeves... slevelets :)
Dress is light-medium Pink.
There are two pre-existing shoulder/contour darts (one over each shoulder) starting at the shoulder seam and extend down back to the waist. The reccomended alteration is two "half-inch" pinch/folds at each of the 2 darts marked at about 3 inches below shoulder blades.
So, my plan is to taper the darts starting at the safety pin marked depth and finish at top shoulder point and same to bottom dart point.
I think my problems are... (1) what to do to lining ? do i make the same alteration ? (2) do i need to rip old dart seams after i finish fitting then cut and press flat or can i just leave them alone ? (3) can i use any old matching color cotton thread or do i need to use silk thread ? (4) will alteration on the silk be easy to undo without marring the fabric ? that is only if the alteration does not seem to work, otherwise it will be considered permanent.
any advice on this greatly appreciated, Rob
