No I'm not really tired of it because I don't pay attention to it. I don't follow "celebrities" and certainly would never entertain buying their mass-produced, poor-quality, overpriced "fashion" that's made in sweatshops somewhere. Those Macy's ads that show "celebrity" after celebrity are clearly not targeted towards me.
I have shopped the same stores since my mid-20s (I'm late 30s now) - Ann Taylor, Talbots, J. Crew and a discount place near me that has off-price designer clothes (real designers, not fake celebrity stuff). Basics come from Target or TJ Maxx. I never have trouble finding clothes that are well made, stylish and classic.
I think that the celebrity lines of clothes target younger buyers who have more disposable income and poorer taste and don't mind wasting money on cheap, poor quality clothing that's only going to be trendy or wearable for a season or two. Older women know their own style, color and fit, avoid trends that don't flatter them or fit their taste and buy for quality, not trendiness. That's why flash-in-the-pan faux designers don't market toward them, and that's fine. Would would really want to buy clothes in the style of Ivanka Trump?
