Like wearing a Star Trek costume

In my humble opinion:
PROs
 A lovely top. Rich red color. Nice texture.
 Well made because it's thick and will definitely keep me warm & insulted on chilly days.
 Great fit

Unfortunately, I am sending this top back, because upon putting this top on, I felt like I am wearing a Star Trek costume. The black pleather trim on the shoulder with the red contrast made me feel like I am prepping for Halloween or a Comic-Con Expo. Also the black pleather trim part is very cheap looking and feeling.

Great quality and I'll be honest, these look cool.  I look like Maverick from Top Gun and literally feel like Tom Cruise when I wear these, minus the crazy parts of him.

First off, I'm no costume designer but the look and fit of this shirt are genuine enough that I think a casual observer would be hard-pressed to notice any flaws in your costume if you decided to film your own new TNG fan series.  Black threads are visible at the seams, but I think that's forgivable for an article in the $25-$30 price range.  I like that the pips are actual pins rather than stickers or embroidered on, and that they include a little reference sheet so you know which ones to use for a given rank or character, in case your memory is a bit rusty or you didn't quite pay attention to those subtle details.  The communicator pin is a heavy rubbery pin, and mine is poorly-painted...but hey, it's still better than a cheesy embroidered-on design, and I suppose I could always touch it up.

I have a hard time describing the fit based on Amazon's answer options to the question, "How does this product fit?"  I'm a 6'1", 175 lbs man with a slight belly and the medium shirt fits well except for the weird armpits.  It's hard to describe, but I think the armpits of the shirt basically extend further down the side of the shirt in order to produce a sleeker look, so when you lift your arms it feels like you're pulling the side outward a little.  Imagine a flying squirrel spreading out its limbs--okay, maybe that's a bit of an exaggeration, but you probably get the point.  Based on the sizing chart, I think the small definitely would have been too small, and I suspect the large probably would have been baggy.  Then again, with free returns I probably should have ordered 2 or 3 sizes and sent back whatever didn't fit.

I understand that I'm a bit biased, but I think the shirt looks great on me if I suck in my gut a little and don't raise my arms any higher than the guy in Amazon's product picture (he has his hands on his hips).  It feels like if I lift my arms much higher than that, the armpits or sides will rip open.  I also understand now why the TNG crew constantly have to tug their shirts down.  The elastic at the bottom of the shirt is probably supposed to hold the shirt down at your waist, but what really happens is that every time you lift your arms or take a deep breath (thus lifting your diaphragm), the shirt rides up your torso and the elastic prevents it from sliding back down.  For better or worse, this shirt seems almost *too* authentic!

I bought this costume for a live action role play, where there's an awful lot of running to do. It's probably the most strenuous test of a costume's comfort I can think of. Here's the short review: Pretty decent costume so long as you don't want to dye it.

Here's a more detailed review:
If you have any intentions of dying this costume, don't bother. The materials aren't water absorbent. I tried to dye it black, and it didn't turn out even a little bit darker. But, of course, it would be wrong of me to rate it poorly because it didn't work well for something the manufacturer didn't intend for.

For the most part, this costume is quite well made. The 'leather' parts are the sort of cheap latex type material you'd expect from a Halloween costume. The gloves are a more comfortable cloth material. My biggest complaint is that the buckles on the front of the vest part are poorly made, resulting in them coming undone every so often. The straight part of the buckle that goes through the hole in the strap isn't in any way attached to the rest of the buckle. If you're crafty, you could probably hack a fix for that, and they do give you a little room to make it fit you a bit more snugly. If you're just using it for a party or some such and not something as active as LARP, it may not give you as much trouble in the first place.

These boots are perfect! They fit comfortably, and with the lower (but not too low!) heel and rubber sole, quite comfortable for standing and walking. The edge doesn't chafe my leg as some people said, and I don't have slender calves, but it seems that a thick sock or a little piece of padding would solve the problem. It's actually roomy at the top edge. I use them for a Star Trek costume, and they look great! Best of all, I didn't have to give up comfort to look the part.

When paired with blue jeans, this costume is instantly recognizable. My husband wore it it a Cubs game, and you wouldn't believe how many drunk guys screamed "Hey, WALDO!" at him and asked to take a picture with him. Like other reviewers have said, the material is a little chintzy. It also has an odd greasy feel when you take it out of the package.

I didn't want to hand wash it, but I was worried about the bleeding that other folks had mentioned, so I got a&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Carbona-Color-Grabber-Reusable-1-ct/dp/B0049N58I8/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Carbona Color Grabber Reusable-1 ct</a>&nbsp;dye-grabbing cloth to throw in the washing machine with the costume. The shirt came out great, but the white part of the hat turned slightly pink. The cloth definitely did its job, though, as it came out a bright pink.

While the polo is not exactly Starfleet spec as a huge nerd I like this shirt very much. I got it as a gift and as it cost me nothing I plan on wearing it until it wears out. Plus the polo allows you to blend into regular society without looking too much like a berk.

Bought this for my brother who got lots of compliments at work.  It says Star Trek but in a more subtle way and goes with a lot of stuff.

I am 5'6" and 135-140lbs. This costume feels really good and has a decent fit. I tried the medium but it was too short; I could barely pull it over my shoulders. The neck piece is uncomfortable so it's best to remove it.  I ended up returning the medium for the large and though it's a bit loose, it suits my height much better. I would have a preferred a tighter fit since the fabric does not sit flat against the small of my back and curve with my body, but that may be just because there's quite a bit of cush in my tush, if you catch my drift. I found that by using the belt to tighten the fabric in that spot, it really makes a flattering fit.

Also, I was planning on using this costume to create a Storm (X-men) costume but after seeing how hot all the pieces are together, I went with being Catwoman!

I got these for a Marty McFly costume but I might wear them more often. I don't want to look like a hipster though.

As stated elsewhere, this is a two piece costume. The "shirt" is only the front half of a shirt, and is sewn into the jacket. If you're a larger person and wondering if this will fit you, I just barely fit in it at 5'10" and 240 pounds. I wore the pants on my hips (like jeans), where I'd normally wear size 38 pants. I got the trousers buttoned and zipped with some effort. The pants fit me quite snugly and  I felt a bit restricted in my movement. The shirt is made of a very stretchy material which allowed me to button it and not look too ridiculous. I was able to button the jacket, but it clearly looked too tight, so I wore the jacket open. The pants are pretty long, possibly to accommodate platform shoes. I usually wear a 30" inseam and was walking on a good 2" of the pants. I'd say this costume would work well for anyone in the Medium to XL size range. I got rave reviews on the outfit as a whole. For the price it seems to be a good value.

I wore this for my in-office Halloween day. It looks awesome walking around and taking pictures with folks. Sitting down the belt thing kind of rides up and there is nowhere to put my keys, wallet, or phone. Great costume, I suggest getting suspenders for holding the pants up. I was planning on wearing this to conventions but I may need to do some alterations to it first.

I'm really torn between rating this a 4 or a 5 on this outfit. So, 4.5 I guess. It is exactly as expected. I'm 6'2 and around 280--this fit just fine. There are two belts, the cloth one, and the leather one. The cloth belt is a little tighter/shorter than the leather one. I thought the tabard pieces were attached but they are loose from the tunic (which isn't bad but it makes restroom visits an adventure). There are no pockets (which I expected but it is important to mention). The material is sort of like suit slacks--so it feels like wearing a marching band uniform. The sleeves and pants are long on me (I have no hands when the sleeves are rolled down).

For the money, this is an incredible deal for an all-in-one "Space Knight" outfit. On Etsy, these are running for close to $200. I think I'll use mine as a base for making something more elaborate. As far as costumes go, this is pretty high quality. There are just some odd things about how it fits that drop it star for me.

This is a well made, nice fitting piece of geekdom. I wear them under skirts and also as pants with a longer blouse, as they don't show much of a panty line.

Final note: if you're fair like me, they kinda resemble tattoos instead of leggings. That's not a bad thing -- just be open to people commenting "Nice tats!"

This is going to work perfectly for my Halloween costume as Missy from Dr Who. I'll just need to fluff it up a bit more and viola!

This is a cool outfit.  The pants are the cheap material, but the shirt has good detail and fits.  The tie was too small for the neck of this shirt.  The adjustable hat is good.
