Simplicity!

 loving the simplicity of this charcoal grey jumper with V neck and button detailing...

 deep armholes means you could wear a tank top underneath...

definitely these black peeptoe booties...

these Superga grey hightops / high top sneakers...

any of these 50 shades of grey tees...

like this black and white striped tank top without getting the jumper sweaty...

 or with a short sleeved denim shirt like this one...

loving the soft light blue wash of this short sleeve denim shirt...

Denim blue crocodile embossed bag

which would look really cute with this floral denim pinafore...

 this button-down embroidered denim jumper / pinafore / pinny dress...

 love the delicate embroidery...

long, elegant lines...

alternatively, this 50" denim pinafore / jumper dress would look cute with the striped tank.

And yes that is an 18" back slit...

loving the cute flap pockets and the zipper detail... 

or this denim dungarees dress...

some may be cinched at the waist with a skinny silver belt...

this French blue driving moc loafer...

and these blue denim clogs should round off the look nicely...

as would these navy blue thong sandals...
