I ALWAYS check the fibre and wash care labels. I was a retail buyer for many years - it’s innate. I don’t always adhere to wash care labels because I’m a careful washer. I also don’t mind eco friendly dry cleaning.
I don’t buy 100% viscose. I don’t buy calf hair, pony hide or real fur.
I try to keep leather to a minimum with shoes and bags. I prefer pleather belts, but they are hard to find. I don’t buy leather jackets, and absolutely nothing made of lambs leather.
I do buy 100% polyester and rayon.
I absolutely believe that polyester has its place, and I’ve written several posts about my point of view. Polyester can be brilliant in blends. Cotton despite being more breathable, is an unstable fibre and not as eco friendly as one would expect. Silk has its challenges too. Personally, I think it’s a dated concept to think that natural fibres are always best. They can fall short in many ways.
Inconsistent quality is unfortunately a reality at any price point these days.
Deal breakers: inferior fabric, shoddy workmanship, bad fit that can’t be altered.
A certain amount of value is important to me too. A Furla bag is exceptional quality. I travel with them very frequently. Sooo robust and polished. I will happily save up for them and pay the high price because I perceive it as value. A $30 top that does not look like it will go the distance offers me little value and that’s a dealbreaker despite the cheap price.
