I think you would appreciate being told about the concept of "retro chic" - doing things the vintage way - in fashion and lifestyle. Using a wicker basket is not incompatible with being modern. Many modern minds reject artificial material. The finest clothes, for example, are most of the time made from natural fabrics and stitched together by hand ("couture"; "bespoke"). There is also "the authentic movement", in music as in lifestyle, whereby music is, for example, played on authentic period instruments (including counter-tenor voices) and interpretations follow more closely (than 50 years ago, for instance) those of the period in which the music was composed. Saddles of the most luxurious bikes, for example, are made from the finest leather, and not artificial materials, and the choice of leather is no less extensive or exquisite than that for a Rolls Royce. I am not saying that the TV series is at that level of sophistication, but the real point about learning a language is to enter a civilsation. The weird thing is not the wicker basket, but the plastic daisies!

Note that it is incorrect to say " the below article". The correct form is "the article below".

One of the most fashionable and best gifts one can possibly give, or receive, is a bespoke wicker picnic basket fully fitted with crockery, cutlery and sterling silver beakers, freshly commissioned from Asprey of Bond Street, London. Look it up on Google Images. Wicker is not dead or out of date.

Thank you so much , Lisa and Kevin

In the nineties, yes, it was probably made of plastic. They were made of wicker before plastic was so available though.That'd be the 1950s, I think? I'm not sure. That was long before my time.
