Bying clothes for teenagers : WHERE ??

1. DS2 has grown up again and I have to change all his wardrobe is I don't want his to look like this cartoon guy with the jeans ending above the ancle...
Basically, he is a small 30W, for an easy 36L...Do you have any idea in which shop I could find this pants.
Last time, quicksilver has the 30/34 which was OK. I hope they will have the 30/36...but doubt, and I would like to find somewhere cheaper as I have to change his wardrobe every 4 months...

2. DD is not even 12 but already a B to C cup - not surprisinly. We had hard time to find some bras which would fit her without being way over her age. Not asking for Mickey or Barbie underwear, which she won't want, but something without embrodery, red, or sexy lace in satin.
We found some in Etam lingerie in Dubai Mall, but did some of you found others shops ?
I just can't believe how sexy the lingerie is nowadays. I don't remember having difficulties to buy some for me when I was her age or even older.
Right now, I buy only at Bravissimo, and I am so pleased with them, and they would have nice bras for her is they were starting with smaller cups. Perhaps you know some "sister company" that will be great for my DD to shop ?

3. I wanted to let you know about a company : spreadshirt.com.
My DD ordered Tshirts from them and we absolutely love them.
She found this company because she wanted to design her own t-shirt and we had a lot of fun designing them with their software.
The idea is that you can choose several kind of Tshirts or other support, then choose from thousands of designs they will put on it, and choose where you want them. You can also download your own design.
You can change the colors, place, ect and see the result instantly.

I'm pretty sure you can find a company that do that here is Dubai, yet, I really like them and would recommend them because :
1. The fabric they use is very good quality (I thought nobody was doing that quality nowdays. But yet, they still do it. They are based in Jamaica, and I think they are like Dominican Republic where you can find really good quality T-shirts are they work for US companies).

2. Service is good. Once my DD put a design where is shouldn't be (accross a zipper), they emailed us, proposed several solutions, one of them being automatically reimbursed if no reply from us within 15 days, which they did.

3. Until now, no problem at all : We had all what we ordered, exactly what we ordered (Prints are good quality too), and were delivered when they said it will be delivered.

It just takes a bit long to be delivered as the cheapest way is to be delivered in US - takes a good qweek-10 days, and then Sns USA-DXB which takes 5 to 7 days too. (which is an eternity for a 11 yo).
