Forty Winks Birthday Celebration
Forty Winks is celebrating its first birthday much like I’d like to celebrate mine —with pretty lingerie and cupcakes. This Thursday, April 14, from 5 to 8 p.m. at the charming Cambridge boutique, customers receive 20 percent off one purchase, whether it’s a flirty bralette from the newly featured line Between the Sheets, a cozy set of loungewear, or lace intimates for a sexy night in. There will be red velvet cupcakes from Sweet and champagne to enjoy while browsing, and the first 100 shoppers will get an Easter-themed gift bag. Turning one year older has its perks.

Forty Winks, 56 JFK St., Cambridge, 617-492-9100,

Trina Turk Trunk Show
Trina Turk’s latest collection of casually sophisticated women’s wear is inspired by the vibrant colors of Rio de Janeiro. From tropical prints to drapey necklines and bold statement jewelry, these styles are great for playing up your wardrobe with fun flair and energy. Beacon Hill’s Wish boutique is showcasing the spring/summer line this Thursday, April 14 from 2 to 8 p.m., and will provide wine and cupcakes for shoppers to munch on.

Wish, 49 Charles St., Boston, 617-227-4441,
