Sitting around the house most days I will wear shorts and knock off football shirts or similar material shirts . Rest of clothes are high street available designers mostly.
I have a wardrobe full of Ralph Lauren polo shirts and Lacoste but find them slightly warm to wear when temperatures are high so don’t wear them much . T-shirts are £20-£100 and vary from nike to Armani/ Versace /boss/Lacoste. Jeans are Levi /Calvin Klein/Armani/boss and vary from £60-£200.
When I see something I like I will usually buy it but here I can’t ever seem to find t-shirts in designer shops that fit , jeans sometimes have size I want but I don’t buy them that often . In the end I usually get friends to bring me out clothes from uk as price will be better and size will fit .
If you are willing to pay more then you are paying for quality of materials and manufacturer usually. The jeans I have that are over £100 are far comfier than the Levi’s as material is softer and stitching when sitting down doesn’t seem to pull at you all the time . Although in some jeans this can be a problem as the jeans can wear quickly in certain areas as material is so soft .
T-shirts are far better as they have a fitted feel and look and material is far better quality and usually great when it’s hot as don’t feel like you are sweating much .
Boxer shorts are also far comfier and last way beyond cheaper ones and the fit is perfect.
As for high end fashion and brands around now I wouldn’t buy them unless won the lottery as the prices are insane . A plain t-shirt with celine or balenciaga written on the front in small letters is £4-600 and if you bought a decent copy for say £25 here then who is going to know the difference unless they know a bit about clothes or basically take the shirt of your back to examine it.
Get what you pay for I guess with designer clothes but obviously a lot is overhyped branding and average quality clothes at mental prices.
