Eleven years old boys sizing in Hollister or SuperDry?

[eleflump]

My up-to-now completely uninterested in fashion ds has suddenly expressed an interest in Hollister and Superdry clothes. He is just about to leave primary school, and so I would like to get him a t-shirt from either one for his leaving disco.

However, they don't seem to do such small sizes and I can only find mens ranges - am I missing something as when I have been searching the MN archives it seems as though these are quite popular brands for this age group?

This is all new to me as I have been merrily shopping in Next and M&S for the last eleven years, (and will hopefully continue to do so in the main!), but I would like to get him a 'going to high school' treat and so any help is gratefully received

x s in mens fits my very tall 12 yr old in superdry

Hollister only starts at small, no extra small. Small fits my 15 year old DS. His 10 year old sister would be totally drowned by it and she wears 11/12 from Boden etc.

My 11 year old is just the same! Not sure about hollister but we went into Superdry and were told to buy women's small, have bought him a hoodie and jacket of eBay which fit well (he is quite slim) be careful with tshirts though some are shaped for a womanly fit!

I ought to clarify Superdry don't do boys sizes hence buying women's stuff all the styles are the same as the men's though
