Costume Photos





Big Sister Ref Sheet


Costume Information

Cost : £160+
Time Taken : 100+ hours

*This costume is officially retired. I don't have time to re-do it, and it takes up a lot of space, so most of it is just getting binned. Considering putting the Helmet up for sale..*

I have decided that I'll most likely be wearing this again at Octobers MCM, but just for the Sunday, since its Halloween and I think that this is adequately scary ^_^

Need to remake quite a few things on this though. Like, ALL the armor. The helmet is still good, so I wont be touching that, but pretty much everything else will be remade again. Will also try making the shorts and top out of pvc, to give it more of a plastic/rubbery look, since it is a diving suit and it's unlikely cotton would really do the trick.

Tank and cage needs a touch up, and all the belts need replacing.

But apart from that, its still good ¬_¬

And it wasnt that hot actually, as long as I didnt have the helmet on, lol. But as soon as I took it off, other people wanted photo's. Was actually so difficult to get around in, lol

This was a pretty tough costume to make. Well done, you did a great job on it. How was it to talk to people - is it easy to just take the helmet off?

by Ranma1-2 on Sunday, 6 June, 2010 - 16:49

the helmet had a strap, but I didn't use it at all, so getting it on and off was pretty easy ^_^

Couldn't hear a thing whilst wearing it though, and I'm pretty sure no one could hear me either, which is good, because I spent most of the day humming and singing songs to myself whilst I was wearing it :P

Oh man, oh man we were walking behind you on the way to expo on one of the days and i was fangirling from a distance xD i never managed to track you down fro a picture, kept getting glimpses of the tank from a distance! Looked really really good though, did it serious justice!

Wow. I really need too take some tips pointers from you as i have no idea were i'm going with mine. This is just epic.

You paid a lot of attention to the detail. Paid off well. I love it.

3 days to go... (Posted 25th May 2010)


So all the body armor and hekmet are painted. THEY ARE DONE.

Currently getting the arm thingies sorted. Im 4 belts short, so need to find them, then I can get the braces done..

then its just a case of knocking up the top and the leg bits. Need to find a way to attatch the braces to the harness though... they fall down if I move :/

Possibly wire or something. I will have a think.

But yeah, I have tomorrow [wednesday] and thursday to get it done, then possibly some time in the hotel if there are any small things I need doing..

Wish me luck..


Oooo EXCITED (Posted 20th May 2010)

I might actually get it all done in time for Expo after all!!

Armor stuff is pretty much done. Just gotta make it pretty :D

Will not be held together with tape at expo :/

YAAAAAAAAAAY (Posted 17th May 2010)

I made a harness thingy!!

I raided my local poundland, got a shit load of leather belts, then bolted them together.

Actually turned out better than I though it would. Just gotta strip them now, and make them nice and brown.

BASICALLY, its the main support for all the shiz that a Big Sis carries around. Its not anything like what its actually supposed to look like, but I think with the leather top/corset thing underneath, it will look pretty awesome. Im going to build all of the shoulder/back armor actually onto it, and the tank and cage will be held on with a combination of velcro and more leather belts. That way I can actully wear it withough them should I so choose.

Hopefully, now Ive gotten this far, Ill get out of this funk Ive been in and actually get the rest of it done.


The helmet has its base colours, tank is half painted, as are the leg armor bits.

Helmet Progress (Posted 10th May 2010)

Helmet is compleatly ready for paint now.

ALSO. Managed to make it so you CANT SEE ME!!

the wonder that is one way mirror stuff :P

PROGRESS REPORT (Posted 7th May 2010)

Helmet has been primered and sanded, ready for a few more coats, more sanding, and eventualy painting.

Basic tank shape is ready, just need to add detail, primer and paint.

need to get started on arm thingy, and eventually the clothing part.


Nearly everything.. (Posted 29th April 2010)

Just ordered some small pressure guages, and little valve wheels, just gotta get hold of a toy steering wheel for the big one now.

White boiler suit has been ordered, will be needing heavy editing.

All thats left to get now is some wood for the leg braces, the wheel, sealant, primer, paint, pleather, then im DONE!!

Lights (Posted 26th April 2010)

Im soooooooo happy with how this is looking atm!!

Only thing is, you can see my face :/ Im gunna have to look into putting another window on the other side of the lights, with like, one way mirror stuff on it, me thinks.

The inside is a mess of electical tape though :/

Helmet Progress (Posted 14th April 2010)

So I actually love this Plastazote stuff :3

Its actually really nice and easy to use. And if you do fook up, you can always reheat it and start again!

Helmet so far. Heated up plastazote in the oven, then places it on the original papier mache helmet with a towel on top to weigh it down. Worked wonders. Use a hot glue gun to fix all the individual peices on. Overlapped a few, and put a bit of glue around the pieces to give it a sort of welded effect. I think it looks pretty good so far!! Might add a few more bits to it today, otherwise Ill wait till the weekend and get some more done :D

DELIVERY!! (Posted 14th April 2010)

Plastazote and foams came today!! Looks like real work will be starting soon!! Just need to get a hold of some decent glue, then its go time :D

Shoes (Posted 12th April 2010)

Spent a while worrying about the shoes for this, then remembered I had these little beauties. Originally they were a shiny black PVC thing, so I used some sand paper to rough the surface up, then used a brown shoe polish. Actually like them better now to be honest.

Heres a before and after shot. Right = before, Left = after.

Im so glad I thought of these, because theyre actually perfect. The white toe cap will be covered with a metal looking cap, so theres no worries about the polish on them :D

Ill do a few more coats of the brown on these as and when, since ive still got over a month to get everything else done.

HELMET FACE HOLE (Posted 12th April 2010)


Its silly

HELMET (Posted 12th April 2010)

Cut out head hole, and marked up all the other bits on it. Im well hapy with how its looking atm.

And its the PERFECT size. Not actually massive like other ones Ive seen :D

Picture of me wearing it, LOL.

Obviously its a rubbish picture, because I couldnt see.. should probably fix that

WAITING D:< (Posted 11th April 2010)

Ordered pretty much everything I need now. Plastazote, modelling foam, red LED lights, perspez is already here :) But yeah, cant like actually do anything now til thats all here
