Yes, try some on, try to imagine that jacket in 50C heat with 90% humidity.
Don't buy gear for just the UK/EU. Ideally, we need different outfits for different conditions. Not practical for traveler.

You want really good venting, waterproof, a few waterproof pockets, good armor and a design that fits Women. (Italian gear best for this)

All the Asian stuff will be cheaper but for FIT, look to Italian brands:
Dainese, Alpinestar and my favorite, Spidi.

First Gear products AFAIK, not sold in UK, but you've plenty other brands. Check out as many as you have time for.

Trousers (especially for Women) are a tough one. I really like Leather and for much of my USA riding, I still prefer my leather pants in many conditions. Love 'em. Good in cold and OK up to about 30C. I use light rain gear OVER them, which adds a layer for more warmth when needed.

For HEAT I wear armored Mesh pants by Sedici (Cycle Gear) It's the Arturo pant. Mesh, armor, perfect fit, well made and CHEAP. Cycle Gear is a HUGE MC chain store here in USA. About 50 stores nationwide. They have "in-house" brands like Bilt, Sedici and a few others. It used to be real crap but now is much better. My Sedici mesh pants are as good or better than much more expensive name brand ones. (mine were $130 usd)

Consider made to measure custom made pants if you want perfect fit and look.
It's hard to carry TWO riding pants on board a bike so pick the right one that will cover all conditions. (not easy!) And don't leave out ARMOR! Knee, hip and tailbone important. Adds heat and SWEAT.
