Trying to work out DD's size? Recommendations for size 14/16 ?

[PinkfluffySlippers63]

DD (16) hates shopping and needs new bra and clothes. We've done the measurements but can't find a decent website to tell me what size these translate into. (EG: Can't find the size guide on Next ). My guess is she's around size 14/16. I know every brand has different ideas on sizing as well. Any recommendations on what's a good brand for this size.....
THANK YOU !

This is the dress size guide from next

I find this site really accurate for sizes

sizes.darkgreener.com/

Is this an age sizing or a dress size?

Boob or bust for bra size and clothing varies between retailers so you will need to look at each companies size charts.

What size was she buying in January/February? Isn't it the same?

I think for a 16 year old new look has nice fashionable clothes and i find their sizes spot on.

Well obviously not Diana only you know what you're implying by that comment. Most teenagers grow, its just the way of the world 🤷‍♂️

What sort of clothes does she like? Next is probably a bit too old... My teen dd really likes Monki (owned by H&M) and occasionally a few things from Urban Outfitters.

Thanks very much everyone for your advice. Really appreciate it. thanks Regal for finding the Next size guide - I couldn't find it for looking!!

Oh I should add that DD has been buying own clothes off Depop /Ebay for ages so that's why I don't know what size to buy for her. Everything has been a guess. However she's finally let me measure her - so now we have a better idea of what size to buy.. And as for why I was asking about Next sizing - it's because hey seem to have nice jeans and we have one local to us. Thanks again. Over and out....
