The Casual Colour Lip and Cheek Colour collection is one of the many collections that launched 
on the 1st day of June,to the best of my knowledge none of the shades have sold out thus far 
so if any tickle your pickle you should be able to pick it up with ease.

All of the shades in the Casual Colour collection are packaged in small round pots that look
more like a lip product than a multi-purpose product - they look very akin to the packaging of Mac's
Lip Conditioners not identical but none the less of the same vain.
I personally don't have any faults with the packaging but I know that some will not find the potted
cream exactly ideal due to hygienic reasons when it comes to applying to the lips.

Mac Keep it Loose is listed on the Mac website as an "Warm Peach" which I fully agree with
although it does have a nice enough yellow undertone to neutralise the shade
lending itself to most skin tones, although I will say that as a cheek shade it may be a little too stark.
This shade reminds me mostly of Mac Crème Cup and for a light shade I really do like it!

As mentioned the Casual Colours are multi-purpose cream products that can be used on the lips
and cheeks, I personally prefer them as a lip product as I found the formula a little too sticky
to be truly comfortable as a cheek shade but that is personal preference.
As a cheek product it felt rather unnatural, like it shouldn't have been used for such purpose.
On the cheeks the sensation was thick, heavy and sticky
with the only redeeming feature being that it dries to a dewy finish that border lined on oily.
On the lips the texture is more natural, light weight and far less sticky yet oddly it settled to a semi matte finish
on my lips rather than a dewy glossy finish which is surprising.
The colour pay off was quite poor, it did take a little building to gain decent pigmentation
even then it was a little streaky and inconsistent, the shade also leans lighter on the skin 
than it does in potted form which was a little of a let down.
The wear time is tricky to comment on as I feel these fair better on drier skin types
as the formula did not work at all with my oily skin, on my lips each application lasted a little over three hours and did not dry out my lips.
I forgot to mention that the Casual Colours have a light vanilla scent, lighter than a typical Mac lipstick.
