In this send: I tried to make sense of the DIY bikini t-shirts I’ve seen online. A true nano-trend. Plus: Costco, Esprit, cufflinks, Char-nel, La Veste, striped tote bags, Nantucket, Kelly Klein, Nikki Chasin, bikini t-shirts, Queen of Sparkles, Asics, Gel-Kayano, fp movement, Aritzia, Abercrombie & Fitch, chewed-up bubblegum, Love, Celine, Dairy Boy, Paige Lorenze, Phia, Want Locker, we love this concealer, The Sheep Detectives, and don’t you just love a random list?

The Rundown:

  • Fresh Receipts — The new deliveries we need to talk about

  • Pop-ups — the newest that have popped-up

  • Forecasting — Bikini Tops, and not what you think

  • Sole Proprietors — Mall Brands expanding into the shoe category

  • Sandals on the Ground Reporting — More insights on Nantucket’s shopping scene

  • In My Feed — Random links worth sharing

Fresh Receipts

  • This went fast: I love a good stud, so I tagged this Polo Ralph Lauren shoulder bag to share and it has already sold out at Net-a-porter (another one here still in stock). This version is less studded, but still very cool. Another iteration that feels almost like the little sister.

  • Gap cues the boombox: Are we ready for this next Gap collab? If it is what it is teasing it could be big for marketing — but you know I want to see the actual merchandise and the execution. We will find out July 16th.

  • Esprit de Costco: Costco has Esprit sweatshirts for $16.99 in store and $18.99 online and Gen X’ers on social media are freaking out. I asked Ana Andjelic, a brand expert and someone who worked at Esprit as the Global Chief Brand Officer what she thought. She told me “Costco is a great distribution channel for Esprit, as it ensures the reach with be wide. And the sweatshirts look amazing and are hitting all the right notes.” I love it when a brand can bring a bit of joy to shoppers.

  • Fresh Sale: Agmes launched their summer sale. In addition to having items on sale, they also have “experiment” items that are one-of-a-kind samples like these cool cufflinks. With button-up and button-down shirts being so of-the-moment (Charvet, Char-nel, Chava, Ralph Lauren) we need more jewelry brands creating cufflinks. In the Agmes sale you will also find archival jewelry and past season styles. These organic pearl earrings are really special too. Use code sale2026 to access the sale here.

  • In(La)Veste in this tote: As I’ve been tracking canvas totes, the La Veste new delivery came across my feed and while the shape is classic the pattern is FUN! And striped!! Just like their pants and shorts are whimsical and more unique, so are these bags. I really love the Pippi Pouch. It reminds me of the Hermès Bolide Pouch.

Pop-Ups (Bonus — with a Substacker!)

Aspen

Kelly Klein + Year of the Flood vintage jewelry will be in Aspen at Goop for a styling and shopping event. Wednesday July 15th from 11-4pm. Enjoy!

Nantucket

Weezie Towels pop-up from July 14-16 at the Whaling Museum July 14th and Hart Jewelry July 15-16th.

Forecasting

Have you noticed an influx of bikinis printed on t-shirts and button-ups this summer? I’ve been spotting more and more available for sale and when I saw this DIY tutorial pop-up on my feed I decided it was time to really see if this is happening.

Note — I’m questioning if this really is a thing because I haven’t noticed any out in the wild. I haven’t come across anyone wearing. But I’m seeing it enough that I wanted to dig in. I asked my thirteen year old and she told me a girl brought one with a green bikini top for color war at her sleep away camp and I thought that was a cute “use case” for wearing the type of t-shirt.

  • I’m calling Nikki Chasin as the original. (We DO NOT consider this the original, but it is still related as a trompe l’oeil bathing suit and t-shirt.)

  • Last summer there was a fun Nikki Chasin x Loeffler Randall collab (hi! Jessie Randall)

  • Coniglio Palm Beach has done a few button-ups with string bikini tops printed on them. Like this one in blue and this orange bikini with a stripe shirt.

  • Tombolo has a playful take on sand dollars.

  • This Free People version reminds me of when you put a t-shirt on after the beach or pool and your swimsuit is still wet.

  • Simon Miller has a playful version on a stripe t-shirt.

  • A brand inspiring some more DIY versions is this brand, Queen of Sparkles, with this version of a top and this cover-up. Anyone want to share more in the comments about the brand Queen of Sparkles? I’m all ears.

  • Target had one in 2025, and now there are tons on Shein! I won’t link, just trust me or go ahead and search.

Sole Proprietors

  • FP Movement has a new collaboration with Asics. The apparel items have the FP Movement style all over them, in a good way. I also like how they have a runners bundle and a tennis bundle. The price points on the bundles are high for their core demographic but I love a bundle to drive up Average Order Value. (I live in Asics Gel-Kayanos — usually the 14, but my latest pair is this one — the Gel-Kayano 20, bought at FP Movement. Their colorways were the best when I was searching.)

    • A few Gen Z focused mall brands have been getting more and more into the footwear category. See: Aritzia, and Abercrombie & Fitch. [CNBC, Glossy, WWD] And of course I have a few additional thoughts to add.
