I spent 1995 and 1996 in Poland, coming there from the US. One of the things that visitors used to comment about was how well the Poles were dressed. How could this be true when they earned so little compared to the visitors?
I found out that there were several answers (in no particular order.
The lack of washing machines and laundramats. When machine washing is not an option, better fabrics like good wools and silks and linens (the types that Westerners dry clean but that actually can be quite easily handwashed) become practical, so the Poles wore more of these. Handwashed clothes stay good looking for a long long time.
The experiences of the Communist years. When you went to the store, you found only 20 size 32 ugly brown dresses in stock. What did you do? You bought one, took it apart, restyled, dyed or embellished it, and wore it. Almost every stylish woman was an experienced desigher-maker for all intents and purposes. They knew quality when they saw it.
Dress-making and tailoring were still viable professions. Getting your important clothes, particularly business attire, made to fit by a professsion maker was reasonably affordable.
The Poles anticipated wearing their clothes over a very long time period of itme and even passing them on to other family members. They wore a huge amount of classics, mostly in a color pallet of neutrals and neutral-friendly (like home furnishing) colors. When you limit your pallet that way, you are always color coordinated.
I took away a lot of lessons and still wear my tailor-made blazer.
