*Disclaimer: I've only visited Color Color the once so if, in five months time, you go and find it nothing like I've describe I apologise...best to go sooner rather than later so as to avoid disappointment*
Color Color sells two types of clothing; your more average high street fashion but also cardigans, blouses, jumpers (and knickerbocker style leggings) in black and pastel shades trimmed with fur, lace, bows, pearls, ribbons and flowers that would fit perfectly in any self-respecting classic lolita's wardrobe (but also good for casual, country and gothic lolitas).
When I went all items were half price (either the shop's shutting down, is having an uber sale or instantly marks items as sale items to get you to buy more) with each item averaging around £25 however I think even their non-sale prices of between £40-£50 are super cheap for lolita-ish clothing.
All items are one-size and I would say fit up to a UK size 14 (40-42). I'd say if you are a flat 16 (rather than a curvy 16) you might fit but I'd definitely recommend trying your chosen item on first to avoid disappointment later. I also recommend anyone with a bra size 36C or above to try on the button ups before buying as...as you will already know if you are curvy up top...button ups can gape.
In retrospect I wish I'd taken some pictures of the clothing I saw to back up my theory that they are suitable for part of a lolita outfit however here is a picture of what I bought (the collar is lace-lined and is detachable so you can wear the cardigan / jacket in spring too. The bottom thing is a pink and purple fur wrap):
And below are some pictures of me wearing it as part of a lolita outfit. This outfit is comprised completely of high street items to show that it is possible to recreate an expensive / unique / subculture style even if you are on a limited budget / cannot sew (the other alternative) / aren't one of those girls who has a wardrobe crammed with Metamorphose, Baby the Stars Shine Bright, Angelic Pretty, *name your favourite brand* clothing thanks to the bank of mum and dad. You just have to learn to be selective and diligent. I know how hard learning to be selective can be - it took me a long time to learn what I could and couldn't pass off as lolita and some lolitas who can afford wardrobes full of the real McCoy can be very cruel...especially with that pesky phrase 'ita' (horrible term - never use it - we were all new to the style once).
Flora crown - Primark
Cardigan / jacket - Color Color
Blouse - Monsoon
Skirt - Joules Boutique (via John Lewis)
Tights - Accessorize (though you can get a variety of thick, coloured tights from most high street stores now - I really recommend Dorothy Perkins and Pretty Polly)
Mary Jane shoes - Rocket Dog
Of course once you learn how to take high street items out of context you can create any style you like, be it completely unique to you, inspired by your favourite subculture (steampunk would be fun to try to achieve), inspired by your favourite celebrity or even by your favourite character. I really recommend learning the basics of sewing too. You can then make basic alterations that can instantly transform a piece that everyone has into something that is completely yours. If you become really brave you can even try making a whole item from scratch - I made a dress inspired by the design of Scarecrow Year One. If not it's okay. Below are two nearly completely high street sourced looks inspired by my great fictional crush and role model Edward Nygma / Nigma aka Riddler:
Bow - Claire's
Glasses - Vogue (via Boots - I'm a speccy four eyes so need to wear them however I know you can get pretend glasses at the fraction of the price should you be so inclined)
Necklace - Etsy (great source of unique and themed fashion)
Shirt - H&M
Dress - Dorothy Perkins
(I also usually wear purple tights with this from DP and purple shoes from M&S)
Accessories are the key for this look (otherwise you just look like a girl wearing a tie lol). If I ever get braver I will add a few question marks to the jacket or a big one on the back!
Hat - Urban Outfitters
Tie - Primark
Jacket - H&M
Satchel - H! by Henry Holland (via Debenhams)
Gloves - Billy Bag London (via TKMaxx...as a devotee of Arkham City Riddler I nearly wet myself when I saw these beauties)
Of course to wear themed outfits you have to be confident - people will feel it is their right to tell you that you look weird / call you names / laugh at you / stalk you - but it is your right to wear whatever you like and you will also find that there will be people who think you look damn cool and wish they were as brave / stylish as you. At first I needed the confidence to wear these clothes in public but wearing them now makes me feel confident and happy to be me...because basically they are me. Fashion is out there to be worn. The high street is out there to be owned.
If all else fails you can be a super geek and take photos of yourself in your themed outfit in dumb poses in the mirror XD
P.S. if you liked this post and would like to see more please let me know. I don't really think I'm qualified to tell people how to dress but I do have a few homemade items (such as the scarecrow dress), lolita outfits and general confidence tips that I would be happy to share :-)
