Well, according to Elsa
It is the Oliver+S Field Trip tee
The size 12 with no mods in a very stretchy cotton/spandex is the perfect fit.
She particularly likes the raglan sleeve.
I particularly like this method to sew the neck band.
A short sleeved version made a groovy sleep top.
My first attempt at freezer paper stencilling.
It won't be my last.
The bottoms are the Oliver+S Sleepover pyjamas sized up to a 14.
Made with some flannelette from Spotlight.
I think I need to work on my placement.....
The tee got quite the work out on our holiday.
