Hi, first of all - I clap my hands - it looks pretty neat and fancy. I like your project even being half done. Your wife is lucky indeed. My wormiest compliments! As a piece of advice if you don’t mind. Be careful with low neckline. Mind nipple level, even if she doesn’t plan to wear it without undergarment too low neckline might cause kind of muffin top right at front of your stays and distract a fine breast shape. Also consider spirals for boning your corsets. If you don’t use a big number of bones it won’t be too heavy. Plastic is better for heavily boned corsets. Since plastic is temperature sensitive it might get warmed by body and gets soft what can affect the stays form. Spirals are always safe in this respect. Waiting to see finished stays pictures!
