Did you take your measurements before buying the pattern?
Ready-to-wear sizes and pattern sizes are sometimes different.
From what I've read, Vogue has the least amount of "extra room" (also known as "ease") built into their patterns. Vogue patterns also have a reputation of being "more difficult" than some of the others.
You might have more success with garment making if you start with something like pajama bottoms or a loose top where "exact" fit is relatively unimportant.
Congratulations on the construction part! :thumbup:
Sorry it ended up not fitting the way you hoped.
Do you have a similar style garment that fits you well? Maybe you could compare the pieces of that one to the pattern pieces and see how/where they differ?
