Wearing wide leg pants with flat slides is a casual and fun throwback to the ’90s. The vibe is breezy, quite elegant, reasonably dressy, practical, and very comfortable. I wore the combination back then, and I’d do so again if I found the right white slides. 

Both outfits below showcase the look well, with one important difference. The wide legs in the first outfit are longer with hems that almost skim the surface of the ground. Visually, I prefer the look of the longer length wide leg pants because it’s somehow luxurious, and lengthens the leg line. But wearing flat slides with the pants is treacherous because the hems get caught under your open heels as you walk. Shoes with closed heels — which in my case are ballet flats, sneakers, or loafers — are a safer, more practical option.

If I sport this combination again, I’ll wear the wide legs a little shorter. The leg line doesn’t look as long, but I’d wear a short top and low-contrast footwear to offset the leg-shortening proportions. In the example below the model is sporting a more practical and short wide leg pant length, where the hems cover the ankle bone but do not touch the shoes. The hems are too short to catch under the open heels of the slides so you can stride comfortably and safely.
