Looking around for patterns or ready-mades for the boys, this is what I came across:
As far as patterns go, Period Impressions has both pants and shirt patterns, which can be found here:
Period Impressions Boys. The review of both patterns are on here:
Great Pattern Review.
Or, if ready-mades look good at this point,
Ott's Sutlery has the best prices, and I've actually seen their finished clothing - they do a good job with them.
I hope that helps, and if there's anything else I can do, just let me know!
God bless!
Love,
Jessica
