No salesperson will take you seriously, want to genuinely help you find your perfect gifts, or sadly even want you handling the beautiful products you reach for.
I'm not saying you need to dress as if you're walking down the road during Mercedes Benz Fashion Week, (I as much as you feel the intense chaos of this time of year)...but even if I'm planning on hitting a late afternoon sculpt class after my shopping cardio to get rid of the excess Christmas cocktails clinging onto my hips...I still manage to dress myself to shop.
Take a bath, brush your hair, dress yourself, throw on a pair of actual shoes, and walk like you intend to accomplish something. You'll get so much more done acting like you mean it, than shuffling along and getting lost in the crowd...or the slumpy poncho you tossed on.
(and manage to snag a handsome billionaire),
you can to!
