I'm not very choosy with the brands of clothes that I wear but when i really like something and the fit is perfect, I buy them in different colors kahit mejo mahal. That goes for tops, shoes, and dresses.
I like kamiseta but I think their clothes are very overpriced to think na the material is not that good the way it used to be. I prefer Bayo much more than Kamiseta nowadays.
I still do splurges even if I have a kid now cus I'm working naman and it feels good to reward myself from time to time. I also buy from tiangges like St Francis and what I normally hoard there are flat shoes kase sa sobrang mura, yung 1k ko 3-4 pairs na yan. Kaya I have a closet-ful of shoes and hinde naman nasisira kagad kase I dont use them everyday, alternate talaga yan.
That said, at the end of the day, I would still go for quality. Kase just like what you've said, most of the time, when you buy clothes from really good brands, assured ka naman of good quality (though not all the time naman). So in the long run, kahit na napamahal ka ng bili, ok lang cus you can use it for a long time.
