What is your most versatile item of clothing

My jeggings and scarves, definitely.
I'd love to try leggings but can't find any I would feel comfortable wearing -any suggestions?

Mine is my denim jacket. I couldn't live without it. I can be worn casually with chinos or leggings and tunic or worn with a pretty summer hmm what that? dress. I never do double denim though.

Leggings and scarves - for all the reasons already given

Scarves of all colours and textures. My velvet ones are the nicest.

They can be used to 'tart up' an outfit, to keep me warm when it is a bit parky outside.

Also I used one as a sling for my 4 year old GS who fell over and made a bit of a fuss. He loved the attention he got with my velvet leopard skin print scarf supporting his poorly arm.

Jeans for me and my long wool cardi doubles up as a dressing gown as well.

I love my leggings, too. I have them in several lengths. I even wear the cycleshort-length ones under dresses if I think I am going to get too hot and sticky, to prevent chafing. I have knee length ones under tunics for gardening, three-quarter length ones and ankle length. I too wear them under trousers in the winter, which means that I can carry on wearing quite thin trousers all year.

I also have an awful of of tunics, so I suppose they are my next most versatile - or is it my long wool cardigans, which double up as dressing-gowns, coats and cover-ups?

Yes, jeans for me too. I've tried leggings but they don't feel or look right on me.

Jeans without a doubt.
