Clothing depends greatly on individual style. Experimentation is key until you find a combination that works for you. In most cases common sense can guide you through dressing non-gendered.
While Neutrois can range anywhere from 'soft butch' to 'flamboyant fop;' the standard daily GenderPunk uniform tends to be 'drab androgyne.' Some interpret it as a relaxed 'soft butch' style. Obviously, ruffles and lace are out (unless you're dressing for a night of signifier play). Tight items are usually out, too. In many cases, your main rule is dark, loose, long, and comfortable.
The purpose of a shirt is to help hide your chest, and obscure your waist. A shirt that fits should be loose, but not too baggy, and long enough to COVER YOUR BUTT. This is the primary reason Neutrois don't tuck shirts. It's important to have your hips and rear hidden so that someone can't tell if they're curvy, or square. If possible, look for shirts where the bottom of the hem is at least 3'' to 5'' below your derriere. Ex-females: Don't be afraid to raid the casual sections of men's departments! The hang range between a women's shirt, a men's normal shirt and a men's XT (tall) can make all the difference in the world. It's also important that the shirt is cut squarely, and that the bottom of the shirt is hemmed straight across. Shirts with rounded bottoms (the type made for tucking) make hip and butt shape more obvious. Avoid them. Also avoid shirts with darts, pleats, and empire seams.
For materials, go loose on knit fabrics, as they tend to cling a bit. Woven fabrics are okay for closer-fitting sizes, provided they can be worn without riding your shape. Stay away from silk. There isn't enough anti-static spray in the world for that stuff. It also reflects your contours more, even when it isn't clinging.
Some Neutrois wear a t-shirt, or a muscle shirt, under a vest, or open, loose button-down shirt. This combination works well, as it helps obscure the body's shape even more. Make sure the base shirt is dark colored, when doing this. If you're wearing light, under a dark, eyes are immediately drawn to the light (and to whatever you're trying to hide). Try to go for black, dark gray, or navy under a drab, like khaki, denim, or plaid flannel. Vests and over-shirts can be colorful and patterned (plaids and houndstooth are great), but be smart about it. Stay away from pastels, florals, and tapestries. Make sure that the vest, or over-shirt are also long and have straight hems.
Depending on how they're cut; pants can make or break you. Anything that fits too closely is a no-no. We suggest staying away from 'flares' as they're made to emphasize hip and buttock lines. Go for square. Cargo pants, or anything cut for a relaxed fit, with straight legs are great. Some people don't like all that material toward the bottoms of straight-cut pant legs. If you're hips are small, go for a slightly tapered pant-leg. Watch those lines and shapes, though. The minute your pants ride your shape, you're a great deal closer to being pegged.
When wearing pants, position them low on your hips. For FTNs, this reduces hip roundness, by not cinching in on the waist. The pants will also hang a little straighter, instead of reflecting the curve they're making over the hips. For MTNs this reduces crotch bulge and keeps things loose and square. If you end up with something that fits great but is too long, go ahead and cuff them. This is cute with overly-long shirt sleeves, too (but avoid overkill). If you don't like cuffs, trimming and hemming is pretty easy to learn.
Shorts are where life gets tough. You can't wear much that's cut above the knee because your leg shape can be a signifier. To be safe, wear them low on the hips and choose items that end at, or below, the knees. Avoid tapered legs, they won't do you any favors with shorts. A cheap option is to take a pair of old jeans, or knit cotton pants, and make knee-length cut-offs. Hem them if you don't like the cut-off look. This is very common when fashion trends push hemlines up. Some people even learn how to sew, so they can make their own clothing at preferred lengths and cuts.
