That is just skin folding, not fat. I recently watched a "fashion makeover" segment on a morning news show (I was captive--it was in a doctor's office waiting room), and a pretty but very overweight woman was getting made over. They put her in an outfit like Selena's above and said the key was having the waist high enough, so that it above the lumpy fat parts. Okay, they didn't use exactly those words, but you get the idea. The message was everyone can wear the exposed midriff style. Sheesh. So, yes, some are trendy no matter what the trend. Call me an old fogey, I guess. Okay, back on topic. My house has has a shade of burgundy that splits the difference between burgundy and plum and a moss green that runs throughout, except bedrooms and laundry/mud rooms. Other stuff is sprinkled in, but those run throughout the house. The floors are light reclaimed wood, but I think darker floors might actually be more appropriate from an interior design standpoint. However, it's a Texas Hill Country house and the pine is appropriate to the genre. So, I'm on board with Marsala, unless it's the browner version.

I don't know about in decor, but radiant orchid (2014) and marsala (2015) showed up in fashion in those years. I didn't see any uptick in their 2016-2018 colors in any setting, though. Coral was really big in fashion a couple years ago, IIRC.

Absolutely not in any way! The house and it's natural light and the preferences of the owner are all that matter.

I think they pick a color that doesn't go with anything that has BEEN trendy so that all the mad trend followers have to run out and get all new things. :-) Also, doesn't Pantone cover not just home dec but also fashion? So often they're not necessarily thinking just about what the color would look like on a wall or a couch, but also as a suit or gown.
