Pre-fall is considered High summer technically and the clothes are usually in-stores around May/June so magazines will promote them. Keep in mind Resort clothes are promoted in magazines as early as November followed by Spring/Summer in January and unless you’re living in the south it’s rather unrealistic lol.
It would make more sense if magazines waited until the clothes were actually in stores when a feature could lead to direct sales. I remember British Vogue wouldn’t even run fall clothes until August. July being their summer issue. This is just magazines trying to feature the clothes before other magazines or celebrities wear them and it’s getting ridiculous.
