Groovy, baby! Smashing tops, Jessie.

   Very 60's is what I thought.  And yes I remember those days! 

I think I’d reprint too.  You would always be wondering.  :thinking:

Welcome to TSP. 
I think dressmakers particularly are critical of their makes and always striving for perfection.  Just look at your RTW clothes for a reality check concerning fit.  I bet yours are better!   

@Lemon Syllabub perfection would be nice wouldn’t it?     I have to say what you’ve ended up with looks really great.  Sewing the elastic down makes a huge difference as it flattens the excess.  Without the extra rows of stitching you get a distorted view of what it will be like. 

I never wear my tops tucked in so it doesn’t matter too much.   I need the excess that elasticated waists create or I can’t sit down!      There is always a trade off between looking sleek when standing and being able to sit down comfortably.  Folks who are nice and slim don’t have quite the same problem.

I’d also recommend a fitting shell however you do it.  A bought pattern is a good starter place.  It may take a while to get it right but it would very useful for adjusting other patterns.  It might also save some money because you could use it and adapt it to other styles yourself!   

Good luck on your trouser journey.

If it was me first I’d throw it in the washing machine and see what happens.  Then steam if that doesn’t work. 

So nice to make something you know works and it makes life easy.
Enjoy your hols. 

@Lemon Syllabub I don’t  think the wide elastic helps.   

If you’ve got a pants pattern that works for you I’d use it.  There’s nothing particularly special about this pattern.
