I have boys clothing, suitable for ages 12-13 :
2 pairs of school trousers (Tu brand) for age 14
- 1 pair black, waist measures about 30", inside seam 24.5"
- 1 pair charcoal grey, waist 29" and inside seam 25.5"
1 pair of Gap jeans, loose fit, age 12, waist 30" and inside seam 25"
4 Gap polo tops, stripy, age 12-13, average measurement 37" chest, 21" back collar to hem
1 Next t-shirt, pale blue with Lego C3PO and R2D2 on the front - Age 12, chest 36" back collar to hem 22"
1 M&S t-shirt, green with surfing penguin - Age 11-12, 34" / 23"
1 M&S t-shirt, black with Raving Rabid - Age 11-12, 34" / 22"
1 M&S t-shirt, pale turquoise with VW campervans - Age 11-12, 34" / 23"
I've given a lot of details because I appreciate that boys this age start to care about what they wear and whether there are pictures on the front or not, and also that age is less indicative of size than when they are younger. Sorry if it seems a bit OTT
