Detailed review: I visited Christina's twice on my month-long visit to the Keys this summer. The first time, I went with a friend (late 60s) who found options both on the outside $2 sale rack and within the well-organized, well-lit store. We recommend that you carefully check the sale pieces as there may be some slight flaws (often easily repaired or stain-treated). Inside, the store is divided into easily navigable sections. To the best of my recollection, there are two-ish racks of men's (pants, shirts, shorts), two racks of plus size mixed styles, and the rest of the store includes standard sizes separated by style and further by "boutique" styles.
Shoes can be found on the display upon first walking in as well as on top of other clothing racks, including boots, flats, loafers, and sneakers. There is a nice array of handbags, including Dooney & Bourke and Michael Kors. They also carry jewelry and other accessories, though I spent most of my time perusing the clothing.
For women's clothes, the Boutique racks include popular brands like Lilly Pulitzer and Free People, as well as Anthropologie brands, Revolve brands, Zara, and some more mature brands like Talbots and Chico's new with tags items. You can also find some of these same boutique brands in the regular sections but they might just be more basic or classic pieces. The boutique section also includes some unique vintage pieces like 100% silk, beaded Stenay, for example. Short dresses line one wall, then tops are divided by sleeveless, short sleeve, and long sleeve blouses. There are layering jackets (lots of Chico's) and a few outerwear pieces (not so necessary in the Keys, but great if you're going north for the holidays). There is a rack of skirts, shorts, and several displays for activewear including sun shirts from brands like Guy Harvey, Columbia, and REI. You'll also find a nice array of sizes in denim including brands like 7 for all Mankind and Levi's. There were also separate displays for rompers and swimwear.
A few more details: Yes, there is a changing room! Yes, the store has options for a wide range of ages and styles! No, the store is not particularly accessible if you use a wheelchair or other mobility support. I'd recommend you call ahead to see how you could be accommodated. No, the racks are not sorted by size aside from the plus-size racks. Yes, there is a rewards program if you enter your phone number! I immediately got a 15% off coupon for my next visit upon checking out the first time. No, the store is not a "true" consignment store; if you want to sell here, you sell your pieces directly to Christina rather than waiting for it to sell to a customer. That means you'd get paid right away (similar to a Plato's Closet). My understanding is that Christina also offers store credit for those who sell to her, so bring in your unused or lightly worn clothing and see what she would be willing to buy!!
Overall, I recommend going to Christina's even if you have to make a bit of a drive (it was about an hour each way for me, but still worth it!). If you love thrifting, you'll be glad of an option in Marathon that has trendy, classic, and affordable clothing in excellent condition. The thrift store a few doors down...not so much. Especially since it was a long drive for me, I was grateful to see detailed reviews and wanted to add one of my own. I wish you happy hunting and I know you'll be happy with both the selection and the prices! Remember, since it's a consignment/thrift store, Christina's inventory will constantly be changing. The brands I listed aren't a guarantee, but my intention was to give you an idea of what you might expect.
Thank you to Christina and to her employee Jill for a lovely and relaxing experience.
