Luckily, there are many gorgeous wedding guest dresses on Amazon that are affordable and deliver within days (with easy returns and exchanges)—saving you the stress of scouring shops, dealing with dressing-room lines, and blowing $300 on a dress you only wear once.

When it comes to shopping for the best wedding guest dress, there are many important considerations, but the primary ones are formality, fit, and finances. You have to account for timing and weather (hot afternoon or cooler evening); location (muddy garden, balmy beach, air-conditioned ballroom?); dress code (black-tie, cocktail, or casual dress). Then factor in the fit: What shape and style best suits your body? Are you looking for an Instagrammable showstopper of a party dress or a more versatile midi-dress or maxidress you can wear beyond the wedding? How big of a priority to you is comfort, breathability, and hitting the dance floor? Lastly, your budget. Being a wedding guest (or bridesmaid) adds up! What you wear should make you feel great without breaking your bank.
