I have had to kit out at several different schools over the years (5 prep schools - 9 schools in total)
I highly recommend going second hand. Most items are well made and last well.
I have never kitted the DC out in all new stuff. Infact at most the schools second hand uniform is more sought after by the children (especially as they go up through the years). They prefer te softer items than the stiff new itchy ones. No school has ever sold on tatty things out of the secondhand shops and the saving financially is very significant.
Infact - last time DD was getting kitted out for her senior school the school uniform shop assistant told me that in 11 years of working there she had that afternoon just fitted out someone in 100% brand new uniform for the very first time.
I was a bit
about the second hand aspect initially but I have to say I think anyone is mad not to consider it first. I did have to buy a new blazer for my DD in her last year of prep school because there were not any her size in the second hand uniform shop and it set me back £139 - it was lovely wool tweed and I tried to make myself feel better that the most I had paid for one before that was £35.
I also sell on through the school secondhand shops once my DC grow out of it. Most school shops only take in items still in decent condition but like I said alot of uniform is decent quality so does definately tend to last several children.
Looking at last terms bill my DD in year 8 at prep school (so the largest/most costly sizes) reads:
School logo tracksuit top £10 (s/h)
School Tracksuit bottoms £7 (s/h)
Games socks £7 (new)
Reversible Hockey Shirt £5 s/h)
I have also enquired about kilts at the start of this year but as yet it looks like hers will see her through (hopefully)
100% wool kilt with leather buckle £48 new £10 to 15 (second hand).
All schools differ - some still charge shockingly high for secondhand and others next to nothing.
Things like tights and socks and some blouses/shirts can be bought mainstream and alot cheaper usually.
Most schoo outfitters are very friendly and honest and will say, Our 2 pack of grey shirts is £32 but most people buy them in M&S or The Lab Coats to my knowledge are not available in this colour anywhere else (and too right I have googled and searched high and low) so you will need to buy the regulation one.
Its best to go with your child and get them fitted. The Outfitters are great at fitting them with enough growing room but too much they look daft.
Good luck.
