The trick to finding a multitude of prom dresses under $100 would be to think away from box: Consider off-the-rack options and dresses that are not necessarily marketed as bridesmaid styles. Wondering where you can buy bridesmiad gowns that won't diminish your crew's wallets? Look to your preferred every day retailers, like Lulus and ASOS, for affordable occasion wear that (bonus) could be worn well following the wedding day—that way, your girls can get the most bang for his or her buck. Just realize that off-the-rack attire could be trickier to change since you will not be ordering the gowns to every girl's unique measurements. (That said, ASOS carries petite, tall, and curvy sizes.)

If you'd like to go the standard route (aka purchase from a bridal retailer), David's Bridal sells gowns under $100 too. Meanwhile, Brideside and The Dessy Group carry styles under $150. (Check out these websites for junior bridesmaid and maternity bridesmiad gowns too.) We also love Birdy Grey, a more recent, on-trend bridesmaid dress site where everything costs $99.

Don't ignore sales, either—discounts may take gorgeous bridesmiad gowns from aspirational to attainable. But if you're looking at going the off-the-rack route or shopping reduced-price dresses, remember that there may 't be enough available to support a bigger bridal party. Another trending selection for inexpensive bridesmiad gowns? Rent the Runway, a rental site that provides marked-down designer attire. It's a nice method to shop more sustainably in case your attendants won't wear their dresses again. But of course, there are some caveats to renting worth bearing in mind. Alterations aren't possible (apart from maybe using some sticky tape) and inventory could be limited. Plus, you might find the delivery date to become a little last second.

Some final words towards the wise? If you're devoted to choosing affordable bridesmiad gowns, you should consider having a mismatched wedding party. Dye lots won't matter and every attendant can select a style that most closely fits their body type (solving size and alteration issues). Overall, you will have way more flexibility (read: more possibilities to score inexpensive gowns).
