Conference outfits (only female attending)

[Kellioo]

I don't know what to wear. All men who will be a mix of shirts and ties or shirts and chinos.

I'm a lower level than everyone else. I'm flattered to be invited but wondering why and have massive imposter syndrome anyway.

I want to look professional, confident and like I belong.

5ft 10in size 10 but some excess lbs so not feeling great.

Budget needs to be less than £100.

If you're looking for inexpensive but very nice wide legged trousers, I'd recommend these - just iron the creases first and they look really smart and are so comfortable. Wear with a belt and shirt - they look good if you've a smallish waist and they skim over everything else. Available in short, regular and long
