HELP A GIRL OUT!! How to dress 2000s and early 2010s??

I really wanna dress 2000s, and i feel like i dont have many 2000s clothes. or at least, clothes that resemble the 2000s. i have:

• two bootcut jeans, one blue, one black (obvs i have more jeans but they dont resemble 2000s)
• a polo shirt (as shown in my pfp)
• a cream v-neck jumper?
• a white and a black scoop neck t-shirt
• this button up shirt, idk how to describe it but i feel like it gives fashion writer editor typa job in the 2000s :p
• my jewellery is a silver necklace with a circle with my name on it, a gold one with a firefly, a gold butterfly ring and a simpler one, and a few gold bracelets, with the exception of a thin silver one with two stars
• uhh apart from that, my clothes are mostly grey varsity jumpers, wide jeans, a grey hoodie, a black jumper with gold buttons on one shoulder, and a few tops, which are cute, but not 2000s.

its also hard to find actual affordable and cute clothes from the 2000s, especially when all the stores in my city look the fucking same. i dont have depop or vinted, and idk if my parents would be happy with me buying second hand stuff, and if im being honest im not that comfortable with buying used stuff.

i live in england and ik compared to other countries, there are many stores that have cute clothing, but here its hard to find :'( does anyone know where to find actual good stuff? help a girl out!!and hey, i do like my clothes, but i wish i could dress more 2000s + early 2010s, but my parents dont really let me bc they think the style looks tacky :'(
