Cyberpunk and Steampunk are usually wrongly related to each other. While they do have an effect on one another and share like-minded admirers, Steampunk is actually an entirely separate movement. Of the 2, Steampunk Costumes is more authoritarian in nature and representative of some sort of that that moves itself down as utopia; when in reality, is ruled below strict laws and rules by the powers that be.
That being said...
Steampunk costumes as a fashion fad appear to be exactly what they represent - a advanced yet underdeveloped style reminiscent of something out of a Jules Verne or HG Wells science fiction novel. Imagine a combination of current Goth and futuristic Goth rolled in to one! The appearance is not objectionable, and actually is type of cool seeking and delivers on an edge! Image Edward Scissorhands meets Elvira Mistress of the black matches Xena the Player Queen matches Sherlock Holmes. Kind of.
It is appropriate to use a vest, but if you don't use one, you should have braces. You may make the vest of some lavish material, like brocade or jacquard, and include a matching cravat. There are many approaches to wrap a cravat, and you should use a broad wrap or a scarf in stead of a cravat, what actually fits your character.
A jacket is fine, but you may also use a military jacket, duster or trench coat. If you are using a trench fur, select a simple one with sophisticated structure or number design at all in the lining, or one with no lining. European style trench fur or operating duster is good.
You need to use many sneakers with laces, but oxfords or boots (with or without laces) are best. Material shoes can be used, although not sneakers.
It's popular to make use of caps when putting on a costume in Steampunk equipment, and as well as the aforementioned top cap and leather helmet, you can pick a bowler or perhaps a fedora. It is advisable to enhance that hat with something, preferably manufactured from steel, like a few equipment wheels or a brooch, but this is simply not necessary.
In the Victorian occasions both sexes applied jewelry. Suitable items for men are the aforementioned wallet view, signet rings, cravat pins and cuff links, if one wears a shirt with sleeves unrolled, and a cravat or tie. It's acceptable for men to use one earring, but it would then be a steel ring, and not a jeweled stud. If you want to wear a hand view, pick a easy design and technical, analog watch, and wear it on a leather strap. Brooches, especially medals, are good. You can even wear a ribbon in a buttonhole, or perhaps a boutonnière.
Pieces and parts
Some of the more common equipment involved with Steampunk clothing is the following:
Spats; old created albeit with a funky Steampunk design
Fingerless gloves, leather needless to say
Buckles, buckles, and more buckles... every where!
Machinist glasses, I don't know what they're riding but obviously they require vision defense
Extended old English fur with tails, top hat or bowler (cane optional)
An altogether different look for Steampunk clothing for a man is of a Victorian driver:
Herringbone cap
Pouch belt; this appears like something one might hold ammunition in, which provides a complete new meaning to the word 'street rage'
White ruffled clothing (with ammo...)
Brown suede jacket with hair collar and 'badge' of types
Another search for men, the 'Studly Gentleman':
Bowler cap, monocle, handlebar moustache
Gray coat with braided arrangements, silver links at each braid-end (reminiscent of civil conflict coat decorative style)
Today for the ladies:
Small skirts which can be frilly however somehow manage to convey a difficult and hard outdoor
Little tops with lots of ruffles and sequined studs emitting the same element
And, you thought it, machinist goggles
Or perhaps:
Small little bowler hat hair pinned to the most truly effective of her head, Janis Joplin-esque round colored glasses
Leather choker with connected gold brooch, leather straps used diagonally from shoulder down to middle (ammunition gear style)
Only a little brown short jacket around a limited small dark dress, and stop bottom, large heeled boots to die for!
Various bobbles, trinkets, badges, pocket watches, brooches, restaurants studded leather supply and arm artists and therefore function as Steampunk jewelryand components
