School clothes - blouses

[JeannieAlogy]

My child has particularly long arms. School require a white revere collar shirt rather than buttoned up style.
Can anyone advise where I might find such a thing? Standard long-sleeved blouses available in supermarkets, etc. are too short in the arm.
Those I have found with extra long sleeves are in boyswear, which I have no issue with but they have the wrong collar style.

Bumping.

To put into context, as an approximation DC is 5ft, but arm span is 5ft 4.

Will she be wearing a jumper over the top? Blazer? If she will wear a jumper, i would get short sleeved blouses until her height catches up with her arms.

Thanks Bigus. Thats what we are doing st the moment.
Short sleeves "slipovers" are the thing to wear rather than jumpers as DC finds the material uncomfortable, hence trying to locate long sleeves.

Have you tried Trutex? My DDs have to have similar and Trutex was one of the few places we can get them from. They do a white long sleeved blouse with revere collar. It doesn't look like they do a longer sleeved version but the size guide does tell you the arm length so maybe you could get away with a size or two larger in the body to get a better arm length??

I buy revere collar blouses from John Lewis. I can't tell you whether the sleeves are particularly long but worth a try

Thanks Dorothea, yes, tried and returned Trutex as the sleeves were well above the wristbone.
I haven't tried JL yet Lab so that may be something to explore.
