    DO NOT BUY (lasted less than 7 months)
    Size: 11, Color: Black, Size: 11, Color: Black
    I bought these for work as a bartender in August of 2025. By December, the tops were scuffed, frayed, and peeling beyond repair, and by February, the soles were coming off. I’ve never had a pair of shoes with such low quality.

    Most comfortable shoes, right out of the box!
    Size: 8.5, Color: Cognac Napa Leather
    Oh my! So, my ordering of shoes online has been hit or miss - 1/2 size too big or too small; too wide or not wide enough. Enter these Marc Joseph shoes… such a game changer. They fit like a glove, exceptionally comfortable, and easy to slip in and out of. I like them so much that I am shopping for another pair. So far, the size, quality, fit, feel, look, and comfort make this pair my dedicated first pick. Btw, I have been wearing them for six hours and they are still very comfortable! I highly recommend these shoes.

    Tropical Fringe Fun for My Summer Outfits
    Color: Natural, Color: Natural
    I am absolutely obsessed with this straw purse because it feels like a vacation in my hand. The first thing I noticed is how the raffia fringe has this playful half moon shape that looks like a little lion mane but in a very high fashion way. My daughter even joked that it looks like a giant fancy taco which makes it such a fun and unique piece to carry around. It is incredibly lightweight which is a huge relief because I do not want to carry a heavy bag when the weather is hot. Even though it looks compact on my mannequin, it is surprisingly roomy inside and fits my phone and all my daily essentials without feeling stuffed. The magnetic closure is quite strong so I do not have to worry about my things falling out while I am walking around a summer party or a night out. The neutral tan and cream colors in the fringe make it very easy to match with almost any outfit I own. I really appreciate the small metal brand patch on the front because it gives the bag a more polished and expensive look than a typical straw tote you might find at a souvenir shop. One thing to keep in mind is that the raffia is very textured so you should probably be careful with delicate silk fabrics so it does not snag. It feels very sturdy and well made for something that is woven from grass and I love how the fringe adds so much movement when I am moving around. This bag is definitely going to be my go to accessory for the rest of the season because it is both stylish and very practical for my needs.
