Party Boutiques Guide
There's something about putting on a costume - even just a hat and a few accessories - that gives people permission to let loose. For Halloween parties, themed birthdays, masquerade events, or dress-up kids' parties, we carry a broad selection of costumes and accessories for all ages and comfort levels. Whether someone wants a full head-to-toe transformation or just a mask and a prop, we have options across both ends of that spectrum.
When outfitting a group, accessories are your secret weapon. A set of matching feather boas or themed headbands creates instant visual cohesion without requiring every guest to buy a complete costume. For kids' parties especially, simple accessories that go over regular clothes are easier for parents and more likely to actually be worn all night.
Sizing is worth double-checking before ordering. Children's costume sizing varies significantly between brands - always check the age and measurement guide rather than relying on S/M/L. For adults, costumes tend to run small. When in doubt, size up - it's easier to adjust a larger costume than to squeeze into one that doesn't fit.
Matching accessories (hats, masks, boas, sashes) create group cohesion without the cost or logistical challenge of coordinating full costumes.
Costume sizing runs small, especially for children. Check measurements, not just age ranges, and go one size up if you're between sizes.
For outdoor or long events, choose costumes that layer over regular clothes. A themed t-shirt under a jacket beats being cold in a character bodysuit.
Popular sizes and characters sell out weeks before October 31st. By mid-October, selection is significantly reduced - plan ahead.
Party Boutiques is at 7724 Yonge St in Thornhill, immediately north of Steeles, with over 450 costumes in stock across adult, kids and infant sizes plus wigs, makeup and masks. We are open seven days a week and easy to reach from north Toronto, Vaughan, Richmond Hill and Markham.
Costume sizing runs small compared to everyday clothing, and children's sizing varies a lot between brands. Work from the measurement guide rather than the age range on the packet, and size up if you fall between two sizes. A costume that is slightly large can be taken in with a belt or a few pins, while one that is too tight cannot be rescued on the night.
Use accessories as the common thread. Matching masks, hats, wigs, sashes or feather boas read as a coordinated group in photographs at a fraction of the cost, and they go over whatever people are already wearing. This works especially well for children's parties, where an accessory is far more likely to stay on all evening than a full bodysuit.

Our team can help you find the right products and quantities in person - no guesswork.
Come in through late September and the first half of October. Popular characters and the middle sizes go first, and by the last two weeks of October the range is noticeably thinner. Shopping in store also lets you check fit and fabric before you commit, which matters most for the costumes people wear for a full evening.
