The Denver Flea isn't so much a market as a party to which everyone is invited — and this year's spring edition blooms with promise. The April 14-15 event boasts a new location — the Denver Rock Drill, at 1717 East 39th Avenue — as well as a slew of first-time vendors offering a fresh batch of quirky or one-of-a-kind items every few feet. And that's not to mention available fare from a battalion of food trucks, as well as brews, craft cocktails and assorted intoxicants courtesy of Great Divide and other experts on imbibing. While it's not free, a single $5 entry fee covers both days of the Flea.

Started by local visual artist Katy Zimmerman and her sister Dena, the @ZimmsVintage Instagram and Etsy-based thrift clothier feels like a secret peek into a tastefully arranged closet. The siblings use their collective eyes for fashion to do the rummaging for you, finding beautiful blazers and perfect pencil skirts for an array of sizes and body types. Katy even customizes some pieces with her visual art, so watch for modified items like her hand-painted purses to show up in the shop, because the pieces go fast. All items are brand-new or gently worn, a mix of vintage staple pieces and fresher apparel, creating an eclectic mix of work-appropriate attire and going-out clothes. The best part? @ZimmsVintage keeps its stock at a nice price point — so you can find a whole outfit from head-to-Doc Martens without breaking the bank.

James Elliott and Stephen Castillo opened their shop on South Broadway in 2008, offering an eclectic mix of gems from the past. Nestled in a bright and colorful stretch of shops, Regal Vintage carries the best trendy pieces from past eras, with fashion stretching from the 1890s to the 1990s. During one stop you might find derbys from the '20s, gold jewelry from the '70s and neon sunglasses from the '80s. The owners strive to ensure that all inventory is fun, fabulous and funky, and credit their decade of success to their connection with the community.

Goldmine, once beloved by Boulder treasure hunters, made the move to Denver last summer, setting up shop in a Broadway storefront in the Baker neighborhood. If you're a Denver-based vintage hound, congratulate yourself on your excellent luck, put on your headlight and grab your pick, because digging through this store is a vintage-miner's dream come true, full of wearable loot from multiple eras hand-selected by Goldmine's traveling buyers. Head to Broadway and stake your claims.

Small is better at the Ten Penny Store, where the vibe is upbeat and, yes, eclectic as all get out. It's not out of order to say that you never know what you'll see there at any given time, but some of it falls in the realms of vintage sports tees, caps and memorabilia; matchbooks from long-gone Denver eateries; pearl-buttoned cowboy shirts; vinyl records and '50s frocks for the ladies. It's that place around the corner that keeps calling you back.

Think of Ninni & Foffa's, named after the owner's Swedish grandparents, as the sweeter side of its neighbor, the Room of Lost Things. Though stuff here sometimes gets a little weird, it's mostly charming: handsome, hand-painted and upcycled furniture pieces; unusual jewelry; vintage nude photography; snarky embroidered samplers and pure, hand-picked and unadulterated treasures from another time. Looking for an unusual gift for your eccentric friend? Hit Ninni & Foffa's, and you'll be in that zone.

Denver retail entrepreneur Shana Colbin Dunn opened her first store, the accessory-heavy Kismet, in 2006 in Highlands Square, and it grew over the years into a three-store Denver metro empire based on good management and impeccable merchandise. But when she moved into Stanley Marketplace last year, it was with a different concept and a new name. True is all about de-stressing and simplifying life, offering clean, beautiful clothing and Colbin Dunn's greatest proven strength — well-curated accessories and jewelry — while also addressing women's wellness through pampering products, books and workshops. It's a cutting-edge business for tough emotional times, and stay tuned: A second True is opening its doors this spring in the LoHi Marketplace in Highland, with more of the same.

Husband-and-wife retail team Stephanie Shearer and Chris Bacorn have years of retail experience between them as the Uptown proprietors of Pandora on the Hill and Soul Haus (big news: Those two stores have merged into one big Soul Haus, with cute dresses, handmade jewelry, haha-funny cards and something for everyone). But it was still a gamble for the couple when they decided to pioneer Stanley Marketplace with a new concept, Trunk Nouveau. They took their marketing know-how and applied it to the shop, tailoring it to a different clientele and the Aurora venue's people-first manifesto, with a wider range of price points and an ever-changing trunk-show theme. But don't worry: The playfulness of Pandora and Soul Haus still runs through the new store's veins.

Molly Hakes first opened Velvet Wolf on Main Street in downtown Littleton, where the boutique gained a reputation for stocking good-looking (but not run-of-the-mill), affordable styles, all topping off at $100, if that, as well as accessories and a house-brand skin-care line. Hakes had no idea what would happen when she committed to moving the boutique to Stanley Marketplace last year, but the location — which impressed her enough to also open Little Wolf, a separate children's store with similar price points and smart curation — has proven good for her brand, good for Stanley and good for the mixed Stapleton/Aurora neighborhood it serves.

As boutiques go, Conservatrice is one of those girly-girl pampering places where a gentleman might buy a gift for his lady love — or the lady herself might go for a moment's respite from the spinning world, among lace and linen, fancy perfume bottles, tinctures and lotions and, to top it all off, redolent floral arrangements perfect for prettying up a boudoir or a wedding reception. Need an all-purpose revitalizing sanctuary in your life? Head to downtown Littleton and shop till you drop.
