Heyy, take a look at this. Those patterned tights are quite hard to pull off but I absolutely love this outfit.
If you want to do it right, do as she did: She picked the framing black color for the cardigan and shoes, and a slightly off yellow (plain) top. The large plain black and yellow areas offset the very busy pattern of the tights while still matching nicely but not too closely. Also, a small black over-the-shoulder purse or a hand-carried wallet would both go so well with this outfit.
Also remember to pack a bunch of smile; nothing beats an outfit like this together with a big smile!
