A mixed blessing

[frualeydis]

Should I be happy that my pink 18th century stays fit me perfectly, so that I won't have to make a new pair? And can use my old bodice pattern. Or should I bemoan the fact that I have regained the weight I lost two years ago?
(To be fair: since they are front-laced over a stomacher the fit is somewhat flexible and they could be smaller in the waist - as it is my waist is half an inch bigger with the stays on than without)
