Would really appreciate help with shopping and style!!

Hello lovelies!! I am in need of a huge wardrobe upgrade. I feel as though I have nothing to wear, yet have so many lame, basic clothes. It seems as though I have no sense of style. Clothes shopping on my own is so OVERWHELMING, I don’t know what to get! I’m not too sure what my style is, but I think it’s like basic Hollister/Urban Behaviour/Forever 21…clothing u can find at these stores. I always blow my money on clothing I don’t end up wearing and I would just like to get a few nice outfits; then i’ll be set!

TLDR; I was wondering if any of you can recommend good clothing stores for teens that mainly have stylish/fancy shirts (cover stomach and chest; not too granny looking) and trendy clothes. Thanks!! Hope you all have a great day!😊 xox💋
