I'm sure there's a subtle meaning here that escapes me...
Underwear. Genuinely a cause for astonishment. Particularly for wearers of the ladies' brand, "LovelyGirl", it would seem.
But perhaps some translation is in order. The debonair (you can tell by the scooter) gentleman to the left has doffed his mohair cardigan and matching driving gloves to casually enquire of his charming companion, "Ty nosíš lovelygirl?". This is Czech for "Are you wearing lovelygirl?"
To which insightful query, she shyly responds, "Ano!!!" or, "Yes!!!"
But I'm sure that the many dedicated followers of fashion who patronise this blog are anxious for a closer view of the tattoo on the gentleman's stomach, in order to more closely inspect such a tasteful and aesthetic example of body-art.
