What were realistic options for a hijabi female rock climber in 2006?

Assalamu alaykum - long shot but worth asking. Hi! I’m Muslim and writing a fiction novel about a Muslim woman who climbs. She’s from England, born and raised, and she starts climbing in an indoor gym in 2006 before moving on to outdoor crags. I got the sense that hijabi sportswear wasn’t common then, so I’m trying to work out what she realistically would have worn and done. Would she have climbed in regular loose clothing (long sleeves and loose trousers) over a sports bra? Would she have adapted men’s gear, like baggy tracksuit bottoms and a long-sleeved tee? Would she have used a scarf tied securely or a cap with a thin underscarf to keep hair covered while staying safe? How would she have handled changing rooms, showers, and modesty at the gym - praying there or finding private spaces, going with a female friend, or avoiding mixed sessions? On outdoor trips, how realistic is it that she’d climb with an all-female group, climb with her husband or a male coach she trusted, or find a local women’s climbing circle? Any thoughts on footwear, harness fitting over modest layers, chalk use, and helmet considerations for hijab wearers at that time? Practical anecdotes, suggested looks that would have been socially acceptable for a practicing hijabi in 2006 England, or small details that would make the character feel authentic would be really helpful. JazakAllah khair for any input.
