I just did an M&S uniform shop in preparation for September as they have 20% off.
For £58 I got:
6x plain white polo tops for DS for
4x trousers for DS for
6x white polo tops for DD
1x pinafore dress
5 girls socks.
I also bought socks a few months ago when they were on sale, 5x white and 5x grey for DD and 5x black for DS, £1.50
.
I need to get tights for DD (should cost less than £10) school jumpers for both DC (£11 each for jumpers/cardigans with the school logo, I will get them 4 each so £88. DD will grow into DS's old ones eventually though), 3 more dresses for DD (probably around £20), summer dresses for DD (around £25) and school shoes (around £35-40 each). They have coats already although DS will need a new light coat in a few months (probably around £25 although I may well find a bargain before then, I love looking for bargains
). DD will need P.E kit, plain white tee, black shorts, plimsolls, around £15. DS will need new plimsolls, £10.
So around £330 altogether for 2 kids.
