Where to look for colourful t-shirts for DD13?

[Lioncubhearted]

She is unimpressed with the H&M collection (too black/beige/white) and stood in the shop asking where the colourful clothes were...
She didn't find anything she liked in the sports shop, nor on the next website.
She's not really developed enough for women's clothes, she does have some but they don't fit quite right.
She doesn't want boy clothes (to be fair, she has a lot of her brother's old stuff) and most of the stuff aimed at unisex is, to her eyes, boy clothes.
No cropped t-shirts, she doesn't want to show her belly button when she lifts her arms above her head.
Not too babyish.

Preferably 100% cotton.

Where do your DD13's get their clothes and what sort of t-shirts do they wear?

Zara kids section
asos if you look around
New Look

Next do loads on their website that they don’t have in the shops. Children’s sizes go up to age 16 online but only 12 in the shops. Someone told me the individual shops vary quite a bit in stock as they decide individually what to display

They have lots of single t-shirts or multipacks - reasonable prices. I do click and collect it’s easy to collect and return unsuitable ones. Prices from £6 approx. Good for leggings too

Uniqlo are good for colourful basic t shirts.

Other options may be White Fox, Hollister etc

What type of tops is she after?
Fitted or boxy fit?
Plain, pictures, all over print or slogan?
What type of colours? (Pinks/ pastels/ primary/ neons)
Can you share a picture of something she does like wearing?

I like Zara kids and Lindex. I hear you though, I feel the same trying to find my 10 year old son tops that don’t have football, gaming or Fortnite on them. We’ve recently enjoyed making tie dye T-shirts which they wear to bed/the beach.

i keep seeing this one advertised

They don’t do kids but maybe a small womens

I was going to suggest next as well who have a full range of colours in T-shirts.

Matalan.... I was in there the other day and the teen range is full of brights and not badly priced

We buy Tu multi packs for boys and girls and the bright colours are there. https://tuclothing.sainsburys.co.uk/browse/kids/girls/multipacks/c:840400/size:14-years/type:t%252Dshirts/ the boys are more vibrant but perfectly normal t shirts for girls/ women too

Look at the boys / men's selections, often better colours, quality and design imo.
