Buying Tip

Frequently Asked Questions

Can you actually wear a t-shirt dress to a wedding?

Yes, for casual and semi-casual weddings, a t-shirt dress works well when you pair it with the right accessories. Add statement earrings, a clutch, and wedges or heels, and you'll fit right in at garden parties, beach ceremonies, and laid-back receptions.

What body type does a casual t-shirt dress look best on?

T-shirt dresses are genuinely flattering on most body types. The relaxed cut skims rather than clings, so it works whether you're petite, plus-size, or somewhere in between. If you want more shape, try adding a belt at the waist.

Is this dress see-through or do you need a slip underneath?

With lighter colors, you may want a nude slip or seamless shorts underneath just to be safe. Darker colors like black or navy are typically opaque enough to wear on their own without any layering.
