A stylist is offering guidance on building a capsule wardrobe, with some outlets suggesting that a limited number of versatile pieces, such as 9 or 10 items, can be sufficient. The stylist's advice may also involve numerical rules, such as the 3-3-3 rule, to help create a functional wardrobe. The specific items and rules recommended for a capsule wardrobe appear to vary, with some outlets highlighting seasonal or investment pieces.
