Where to get trousers for slim 13 yo

[Adesignforstrife]

DD is around 5'3" and slim. Her "age 13" trousers are getting too short. And any kids sizes bigger than that are way too baggy on her. She likes comfortable clothes with no embellishments. Her favourite trousers are some light denim coloured cuffed ankle trousers from h&m and some skinny cord leggings from lands end. I think she may need a small women's size. But where can I look that is neither frumpy nor over-styled? She hates shopping so would have to be something we could look at on line.

These jeans might fit her, you can check waist sizes using the tool on the website

the trousers in age 13-14 may also fit, or you could go for the size up and get the waist taken in

Primark? My teen has been wearing Primark jeans for years.

Yes, similar problem here and another vote for Primark jeans - go into the ladies section (not the kids dept) and get the smallest size there.

or Top Shop petite range - you can pick the waist and leg length.

Topshop petite or any adults petite range, Id stick to more teenager shops. Or hollister/abercrombie petite range?

A size 8 has a similar waist and hip size to an age 13 according to river island. Maybe would more need a 6 but theres no reason she cant move up to adults clothes now
