El_Pickerel's point is very good. Most lenses reach their spot of focus at f5.6 - f8, and can actually be quite soft at the smaller apertures, so much that for critical publishing, unless you were using a lens designed for small aperture work such as micro lens, you're really want to, in broad strokes, shy away from using apertures above f11 unless there were compelling reasons.
Increasing depth-of-field for your fashion work might be better by using wider lens and prime would be my choice for that, too. There would be a slight, but distinct edge on the sharpness throughout the DOF at f5.8/f8 with a 35 or 24, and although you would be hamstrung with working yourself to work the compositions, the look you're describing would be better achieved. IOW, you could use the lenses' optimal apertures to get the optimal sharpnesses for all the pictures you are pre-visualizing, without sacrificing anything.
Going the other direction, using more 'telephoto' zoom lenses opens more aberrations, softness, and leads to ultimately a disappointing path. You'd still have some nice lenses - tools for other uses, but not for what you have described.
