Leighton Meester sure knows how to pull every ensemble really well even on casual days. Here she is again, proving it as she was spotted wearing her plain long-sleeved top, dark-washed studded jeans, high-heeled boots, and finished with a purple Proenza Schoulder PS1 Bag.

The ensemble is understatedly elegant, and the bag surely pops out from her block-colored outfit. Proenza Schouler PS1 bag has already gone through a lot of renditions and this obviously fits perfectly for fall since purple is indeed a key color for the season.

This bag is made from suede, so the sumptuousness of its shade is even more shown. It is complemented with some gold-tone hardware, giving this bag more luxurious look.

It goes the same as with other versions of the PS1, which comes complete with front straps, flap, and a lot of pockets for storage. This can be carried either through its short top handle or through the long adjustable shoulder strap for hands-free option.

The fall and winter season requires outfits that come in block shade to keep you in the vogue; but so as to let you standout, perhaps doing the same thing that Leighton Meester did in this shot, which is carrying a really striking purse, could do the job.
