If a rip in the fabric of time is what allows time travel, then sewing a patch on that rip is the only thing preventing Franklin Pierce from riding a steam train into the present, where he'd still be America's most forgettable president. Mend the fabric of time and the fabric of pants with today's Groupon: for $20, you get $40 worth of garment alterations at Mimi’s Alterations.

Mimi’s Alterations’ skilled seamstress draws on more than 30 years of garment-alteration experience to adjust duds with speedy service and a keen eye for detail. The handy needle wielder expediently hems jeans ($20) and lined slacks ($30), renovates skirt waists ($35), and shortens jacket sleeves ($30), putting finely chiseled carpal muscles on display to intimidate rival grocery shoppers. Suit backs with spare material at the seams can be let out or taken in ($45), and dress lengths can diminish ($35 with lining, $30 without) to flatter physiques of any stature. The experienced clothier, adroit at altering gowns and formal attire, has been known to create wedding dresses from scratch or from melted marshmallows, and brides-to-be can call upon the shop’s nuptial-attire-adjustment capabilities by applying today’s Groupon toward the full cost of wedding-dress alterations.

Though Mimi’s Alterations sometimes features a discounted price online, this Groupon still offers the best deal available.
