折腾implies determination, initiative and perhaps even some successful outcome, I’m not going to suggest a word in English (because someone would probably dictionary whatever I suggest and use it as a weapon lol) but sure there are phrases you can use. Being around for only a few days I do find some of the crowd here are people that do not appreciate languages are just tools and dictionaries like maps mean nothing except what was said on paper. No wonder C-E translation has been bad ever since 嚴復 started it all. Maybe it applies to all languages. I am wondering…… But surely even among my own friends there are lots nice and learned people, so shame on me (for being vain in comparing myself against some of the people here) and all the best to everyone else. I'm bored and coutning seconds to get off work! 88

"折腾"是非常口语的一个词，在中国北方（或东北）用得较多，比较难找到一个非常精确的英文词与之对应，而且不同的语言环境下，表示的也不一样。但是这里可以理解为“style herself or pamper herself”, she is very good at styling herself, showing herself off

in general (not necessarily fit for this context):
the restless type
never settles for mediocrity
ever the overachiever
the nonconforming type
always on the move (on her feet)
the type that is always working on something

Chinese term (edited): 能“折腾”的人

能“折腾”的人在这里的意思应该是追求时髦,经常出入社交场合的人

I would opt for either.
Spendthrift is more negative, and Extravagant has a more positive connotation.

Spendthrift:
One who spends money profusely or improvidently; a prodigal; one who lavishes or wastes his estate. Also used figuratively.

Extravagant:
Given to lavish or imprudent expenditure: extravagant members of the imperial court.

(She is) fond of showing off

折腾 意即 炫耀、卖弄
